Poly[[[mu]2-acetato-aquadi-[mu]3-isonicotinato-erbium(III)silver(I)] perchlorate]

L.-C. Zhu

Abstract top

In the title three-dimensional heterometallic complex, {[AgEr(C6H4NO2)2(C2H3O2)(H2O)]ClO4}n, the eight-coordinate ErIII ion adopts a distorted bicapped trigonal-prismatic geometry, being coordinated by four O atoms from four different isonicotinate ligands, three O atoms from two different acetate ligands and one O atom of the water molecule. The two-coordinate AgI ion is surrounded by two N atoms from two different isonicotinate anions in a slightly bent configuration. These building blocks are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network. Ths structure is consolidated by O-H...O hydrogen bonding between the coordinated water molecule and a carboxylate group of the acetate ligand. The perchlorate anion is disordered over two sites with site-occupancy factors of 0.526 (13) and 0.474 (13), while the methyl group of the acetate ligand is equally disordered over two sites.

Comment top

In the past few years, lanthanide-transition metal heterometallic complexes with bridging multifunctional organic ligands gained increasing interest, not only because of their crystal structures, but also due to their applications in ion exchange, magnetism, catalysis and as luminescent material (Cheng et al., 2006; Kuang et al., 2007; Peng et al., 2008; Zhu et al., 2009). As an extension of this research, the structure of the title compound, a new heterometallic coordination polymer, (I), has been determined and is presented in this article.

In the title compound (Fig. 1), there are one ErIII ion, one AgI ion, two halves of an acetate ligand, two isonicotinate ligands, one coordinated water molecule, and one perchlorate anion in the asymmetric unit. Each ErIII ion is eight-coordinated by four O atoms from four different isonicotinate ligands [Er—O distances ranging from 2.266 (3) to 2.308 (3) Å], three O atoms from two different acetate ligands [Er—O distances ranging from 2.341 (3) to 2.454 (3) Å], and one O atom of water molecule [Er—O distance 2.369 (3) Å]. The Er center can be described as having a distorted bicapped trigonal-prismatic coordination geometry. The two-coordinated AgI ion is bonded to two N atoms from two different isonicotinate anions [Ag—N distances 2.153 (4) and 2.154 (4) Å] and adopts a slight distortion from linearity with an N1—Ag1—N2 angle of 165.44 (19) °. These metal coordination units are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network (Fig. 2). The coordinated water molecules exhibit O—H···O hydrogen bonding to the uncoordinated O atom of a carboxylate group and to the acetate ligand (Table 1).

Experimental top

A mixture of AgNO3 (0.057 g, 0.33 mmol), Er2O3 (0.116 g, 0.33 mmol), isonicotinic acid (0.164 g, 1.33 mmol), CH3COONa (0.057 g, 0.7 mmol), H2O (7 ml), and HClO4 (0.257 mmol) (pH 2) was sealed in a 20 ml Teflon-lined reaction vessel at 443 K for 6 days and then slowly cooled to room temperature. The product was collected by filtration, washed with water and was air-dried. Colorless block-shaped crystals suitable for X-ray analysis were obtained.

Refinement top

H atoms bonded to C atoms were positioned geometrically and refined as riding, with C—H = 0.93 or 0.96 Å and Uiso(H) = 1.2 or 1.5 Ueq(C). H atoms of water molecules were found from difference Fourier maps and refined isotropically with a restraint of O—H = 0.81 - 0.82 Å. The perchlorate anion is disordered over two sites with site occupancy factors 0.526 (13) and 0.474 (13), whereas the methyl group of the acetate ligand is disordered over two sites with site occupancy factors 0.51 (5) and 0.49 (5).

Special details top

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.
