The title compound, catena-poly[[[di­aqua­(methanol-κO)cop­per(II)]-μ-N-(4-methyl­pyrimidin-2-yl-κN¹)pyrazin-2-amine-κ²N¹:N⁴] [[aqua­(aqua/methanol-κO)(perchlorato-κO)cop­per(II)]-μ-N-(4-methyl­pyrimidin-2-yl-κN¹)pyrazin-2-amine-κ²N¹:N⁴] tris­(perchlorate) methanol monosolvate 1.419-hy­drate], {[Cu(C₉H₉N₅)(CH₃OH)(H₂O)₂][Cu(C₉H₉N₅)(ClO₄)(CH₃OH)_0.581(H₂O)_1.419](ClO₄)₃·CH₃OH·1.419H₂O}_n, is a one-dimensional straight-chain polymer of N-(4-methyl­py­rimidin-2-yl)pyrazin-2-amine (L) with Cu(ClO₄)₂. The complex con­sists of two crystallographically independent one-dimensional chains in which the Cu^II atoms exhibit two different octa­hedral coordination geometries. The L ligand coordinates to two Cu^II centres in a tridentate manner, with the pyrazine ring acting as a bridge linking the Cu^II coordination units and building an infinite one-dimensional chain. Extensive hydrogen bonding among perchlorate anions, water mol­ecules and L ligands results in three-dimensional networks.

S1. Introduction

Metal–organic frameworks have been studied extensively over the past several decades (Cairns et al., 2008; Dalrymple & Shimizu, 2007; Xie et al., 2004) because of their potential applications in a wide range of areas, including catalysis, separation science, gas storage, drug delivery, molecule-based optical and magnetic materials etc. (Kesanli & Lin, 2003; Brammer, 2004; Gimeno & Vilar, 2006; Kitagawa & Matsuda, 2007). The factors affecting the structure and packing of molecules in crystallization are intricate and are still not clearly understood. Different structures can result from changes to any one of a numbers of factors, i.e. solvent, acidity, ratio of the rea­cta­nts, carbon backbone of the ligand and so on (Ouellette et al., 2007; Zhao et al., 2008). Nitro­gen-containing heterocyclic ligands have proved to be extremely versatile, with the abilities to build extended networks with different coordination modes and to mediate significant magnetic inter­actions between paramagnetic centres separated by more than 6 Å (Carranza et al., 2004). A wide variety of nitro­gen-containing heterocyclic ligands have been used to construct coordination polymers, such as pyrrole, pyrazole, pyridine, pyrimidine, pyrazine, and so on (Wang et al., 2008; Ismayilov et al., 2006). Originally designed for the synthesis of extended metal atom chain complexes (EMACs), oligo-α-pyridyl­amine compounds have been shown to be excellent coordination ligands. Recently, a series of modified ligands, viz. oligo-α-pyrazyl/pyrimidyl/pyridyl­amine, have been developed by grafting pyrazine or pyrimidine into the ligands instead of pyridine rings (Ismayilov et al., 2007; Wang et al., 2007, 2012). Containing more atoms capable of coordination, these molecules showed abundant coordination modes, especially in the construction of one-, two- and three-dimensional coordination polymers. Here, a one-dimensional copper(II) complex of N-(4-methyl­pyrimidin-2-yl)pyrazin-2-amine (L) is reported, namely {[Cu(L)(MeOH)(H₂O)₂][Cu(ClO₄)(L)(MeOH/H₂O)₂(H₂O)](ClO₄)₃.MeOH.1.419H₂O}_n, (1), which provides a rare case consisting of two independent one-dimensional chains with different coordination geometries.

S2. Experimental

S2.1. Synthesis and crystallization

A mixture of N-(4-methyl­pyrimidin-2-yl)pyrazin-2-amine (0.10 g, 0.58 mmol) and Cu(ClO₄)₂.6H₂O (0.24 g, 0.65 mmol) in methanol (50 ml) was stirred overnight. The solution was then filtered to remove insoluble impurities and concentrated under vacuum. Slow evaporation of the solution gave crystals suitable for X-ray diffraction.

S2.2. Refinement

The equatorial plane of the Cu2 complex found in the chain is defined by three N atoms (N6, N7 and N10) and by the coordinated disordered water/methanol molecules (O5, O5–C20) with 0.419 (6) water and 0.581 (6) methanol occupancies. A perchlorate anion coordinated to Cu2 as an axial ligand is disordered over two positions (Cl4/O18/O21 and Cl4'/O18'/O21') and was treated with 0.529 (4) and 0.471 (4) occupancies. Atoms O21 and O21' were restrained to have similar displacement parameters. The displacement parameters of the atoms in the disordered perchlorate anion were constrained to be equivalent. One uncoordinated methanol solvent molecule was found to be disordered over the two positions O23/C21 and O23'/C21' and were treated with 0.581 (6) and 0.419 (6) occupancies, respectively. Bond distances involving non-H atoms in the disordered methanol molecules were subjected to distance restraints. The C—O distances within the two components of the disordered methanol solvent molecule (O23—C21 and O23'—C21') are restrained to 1.45 (1) Å and the methanol molecule was modeled with isotropic displacement parameters. Water atom O24 had a short contact of 2.14 Å with methanol atom O23. The free variable for the occupancy factor of uncoordinated water molecule O24 was applied and the occupancy was 0.419 (6) and the atom was refined with an isotropic displacement parameter. H atoms bonded to the coordinated and uncoordinated water molecules were located in difference Fourier maps and the O—H and H···H distances were restrained to be 0.85 (2) and 1.35 (2) Å, respectively. The U_iso(H) values were set at 1.5U_eq(O). H atoms bonded to C and N atoms were positioned geometrically and refined using a riding model, with C—H = 0.95–0.98 Å and N—H = 0.88 Å, and with U_iso(H) = 1.2U_eq(C,N) or 1.5U_eq(methyl C). The refinement of the H atoms of the methanol solvent molecule required the inclusion of inter­molecular restraints to avoid convergence to unreasonable inter­molecular H···H distances. The inter­molecular H···H shortest contact distances were restrained to 2.25 (2) Å.

S3. Results and discussion

The reaction of N-(4-methyl­pyrimidin-2-yl)pyrazin-2-amine (L) with Cu(ClO₄)₂ results in a coordination polymer consisting of two crystallographically independent one-dimensional chains along the c axis, denoted chains (I) and (II); the atom-numbering scheme is shown in Fig. 1. In chain (I), the Cu1 atom is o­cta­hedrally coordinated by two pyrazine N atoms [N1 and N2ⁱ; symmetry code: (i) x, -y+1/2, z+1/2] that are trans to each other, two cis water molecules, a pyrimidine N atom and a methanol O atom. The axial positions are occupied by one water molecule (O2) and one methanol molecule (O3). Elongation occurs along the axial positions due to the Jahn–Teller effect, which is typical for a Cu^II complex (electronic configuration d⁹). This phenomenon was observed in both chains. The coordination geometry and bond lengths are consistent with data reported previously for similar complexes (Wang et al., 2008; Ismayilov et al., 20060 (Table 2). The L ligand acts as a tridentate ligand, coordinating to atom Cu1 via two N atoms and bridging to a symmetry-related Cu1ⁱⁱ atom via the second N atom (N2) of the pyrazine ring [symmetry code: (ii) x, -y+3/2, z-1/2]. Thus, through the pyrazine ring, the coordination units form an infinite one-dimensional straight chain polymer. Atoms N3 and N4 both remain uncoordinated. The straight chain structure is similar to that obtained from middle-ring pyrazine-containing oligo-α-pyridyl­amino ligands, where it was reported that the methyl group and pyrimidine ring contribute little to the formation of the polymer of analogous ligands (Wang et al., 2008).

The Cu^II atom (Cu2) in chain (II) also adopts a six-coordinate o­cta­hedral geometry, in which the coordination mode of the L ligand is the same as that in chain (I), i.e.. the L ligand coordinates to atom Cu2 as a tridentate ligand, chelating to one Cu centre via a pyrazine and a pyrimidine N atom, with the second pyrazine N atom (N7) coordinating to a symmetry-related Cu2^iv atom, thus creating an infinite one-dimensional straight chain [symmetry code: (iv) x, -y+3/2, z+1/2]. Atom Cu2 is o­cta­hedrally coordinated by two pyrazine N atoms (N6 and N7ⁱⁱ) that are trans to each other, a water molecule (O4), a coordinated disordered water/methanol molecule [O5: 0.419 (6) water and 0.581 (6) methanol], a pyrimidine N atom and a perchlorate anion. The perchlorate anion coordinates weakly to atom Cu2 with a relatively long Cu2—O19 distance (Table 2). This weak coordination bond is presumably due to the poor coordination ability of perchlorate counter-ions and the Jahn–Teller effect of the Cu centre, and has been observed in other related complexes with even longer Cu—O distances of 2.573 (5) and 2.588 (2) Å (Wang et al., 2008; Ismayilov et al., 2006).

Extensive hydrogen bonding is observed among the perchlorate anions, water molecules and L ligands (Table 3, and Figs. 2 and 3). The one-dimensional straight chains are linked along the a axis through inter­chain water–perchlorate O2···O7 hydrogen-bonding inter­actions. This is propagated by a water–perchlorate O1···O20ⁱⁱⁱ hydrogen bond [symmetry code: (iii) -x, -y+1, -z+1] resulting in a two-dimensional sheet parallel to the ac plane. The resulting two-dimensional sheet is then hydrogen bonded to other sheets through inter­actions with the inter­stitial perchlorate anions and water molecules. Atoms N3 and N8 and coordinated water molecule O2 form hydrogen bonds to the inter­stital perchlorate counter-anions. Coordinated water molecule O1 forms a hydrogen bond to water molecule O22, which in turn forms a hydrogen bond to the inter­stitial perchlorate anions. This series of hydrogen bonds among the components of the structure results in the three-dimensional hydrogen-bonded network.

In summary, with five N atoms, the L ligand shows a versatile and rich coordination chemistry and supra­molecular structure constructed by hydrogen bonds, which allows for a variety of potentially tunable coordination polymers.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
