In the title complex, [Ni(C16H36N4)(H2O)2][Ni(CN)4], the [Ni(teta)(H2O)2]2+ cations (teta = 5,5,7,12,12,14-hexa­methyl-1,4,8,11-tetra­azacyclo­tetra­deca­ne) and [Ni(CN)4]2− anions are arranged in an alternating fashion through electrostatic and N—H⋯N and O—H⋯N hydrogen-bonding inter­actions, forming a two-dimensional layered structure. Adjacent layers are linked through weak van der Waals inter­actions, resulting in a three-dimensional supra­molecular network.

Comment top

In the past decades, there has been a continuous interest in the utilization of cyano-containing building blocks for constructing either ion-paired or cyano-bridged assemblies due to their potential applications and intriguing architectures (Lescouëzec et al., 2005; Liu et al., 2008; Xu et al., 2009). It has been found that cyano-bridged bimetallic assemblies, derived from tailored cyanometalate entities [MLp(CN)q]n- (L = polydentate ligand) and unsaturated coordinated complex [M'(L)]m+, possess extraordinarily excellent magnetic properties such as SMM (single molecular magnets) and SCM (single chain magnets). Recently, we had expected to obtain such low-dimensional system using [Cr(salen)(CN)2]- (Yamada et al., 1969; Ni et al., 2008) and [Ni(teta)]2+ as the building blocks. However, an unexpected tetracyanonickel(II)-based complex of [Ni(teta)(H2O)2][Ni(CN)4] instead of any [Cr(salen)(CN)2]--based complex was obtained. So far, Jiang et al. (Jiang et al., 2005; 2007) have reported several complexes based on the direct assembly of [Ni(CN)4]2- and [Ni(teta)]2+ building blocks, and they found that all these complexes showed cyano-bridged structures. In contrast to these reported complexes, the title complex of [Ni(teta)(H2O)2][Ni(CN)4] is ion-paired and its crystal structure is reported here.

The title complex consists of [Ni(teta)(H2O)2]2+ cation and [Ni(CN)4]2- anion (Fig. 1). In [Ni(teta)(H2O)2]2+ cation, the NiII ion assumes a distorted octahedral coordination geometry, in which the equatorial sites are occupied by four nitrogen atoms of the macrocyclic ligand teta with the Ni(2)—N bond distances of 2.067 (3) and 2.100 (3) Å, while the axial positions are occupied by two oxygen atoms of water molecules with Ni(2)—O distance of 2.183 (2) Å. As usual, [Ni(CN)4]2- anion exhibits a square planar structure, where all four cyano groups are terminal ones, with Ni(1)—C(1) and Ni(1)—C(2) distances of 1.862 (3) and 1.869 (3) Å, respectively. The Ni(1)—C—N bonds deviate slightly from linearity with the bond angles 177.2 (3) and 178.1 (3)°. [Ni(teta)(H2O)2]2+ and [Ni(CN)4]2- are arranged in an alternating fashion, forming a two-dimensional layered structure through electrostatic and hydrogen bonding interactions (Fig. 2). Furthermore, adjacent layers are linked through weak van der Waals interactions, resulting in a three-dimensional supramolecular network (Fig. 3).

Experimental top

A solution of Ni(teta)(ClO4)2 (0.05 mmol) in DMF (10 ml) was added to a solution of K[Cr(salen)(CN)2].H2O (0.05 mmol) in MeOH/H2O (1/1(V/V),10 ml) mixture. The resulting solution was filtrated and the filtrate was left to allow slow evaporation in dark at room temperature. Pink prism crystals of the title complex were obtained after two weeks, washed with MeOH and H2O, respectively, and dried in air. Anal. Calc. for C20H40Ni2N8O2: C, 44.32; H, 7.44; N, 20.68; Ni, 21.66%. Found: C, 44.28; H, 7.49; N, 20.71; Ni, 21.52%.

Refinement top

All non-H atoms were refined anisotropically. The C(H) atoms of the teta ligands were placed incalculated position [C-H = 0.99 Å or 0.98 Å] and refined using a riding model, with Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(C). The N(H) atoms were located from the difference Fourier maps, and refined as riding with Uiso(H) = 1.2Ueq(N). The O(H) atoms of the coordinated water molecules were located in a difference Fourier map and refined as riding [O-H = 0.84 Å], with Uiso(H) = 1.5Ueq(O).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
