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

L.-C. Zhu

Abstract top

In the title three-dimensional heterometallic complex, {[AgDy(C6H4NO2)2(C2H3O2)(H2O)]ClO4}n, the Dy(III) ion is eight-coordinated by four O atoms from four different isonicotinate ligands, three O atoms from two different acetate ligands and one O atom of water molecule. The two-coordinate AgI ion is bonded to two N atoms from two different isonicotinate anions. These metal coordination units are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network. The coordinated water molecules link the carboxylate group and the acetate ligand by O-H...O hydrogen bonding. The perchlorate anion is disordered over two sites with site occupancy factors 0.508 (12) and 0.492 (12) and the methyl group of the acetate ligand is disordered over two positions of equal occupancy.

Comment top

In the past few years, lanthanide-transition metal heterometallic complexs with bridging multifunctionnal organic ligands are of increasing interest, not only because of their impressive topological structures, but also due to their versatile applications in ion exchange, magnetism, bimetallic catalysis and luminescent probe(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 which is presented in this article.

In the title compound (Fig. 1), there are one Dy(III) ion, one Ag(I) ion, two halves of acetate ligand, two isonicotinate ligands, one coordinated water molecule, and one perchlorate anion in the asymmetric unit. Each Dy(III) ion is eight-coordinated by four O atoms from four different isonicotinate ligands [Dy—O distances ranging from 2.297 (3) to 2.348 (3) Å], and three O atoms from two different acetate ligands [Dy—O distances ranging from 2.394 (3) to 2.484 (3) Å], and one O atom of water molecule [Dy—O distances 2.414 (3) Å]. The O—Dy—O bond angles are in the range from 52.70 (10) to 155.05 (10) °. The Dy center can be described as having a bicapped trigonal prism coordination geometry. The two-coordinate Ag(I) ion is bonded to two N atoms from two different isonicotinate anions [Ag—N distances 2.163 (4) Å]. Thus the Ag(I) ion is in a somewhat linear configuration with N1—Ag1—N2 angle 165.40 (17) °. These metal coordination units are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network (Fig. 2).The coordinated water molecules link the carboxylate group and acetate ligand by O—H···O hydrogen bonding (Table 1). The perchlorate anion is disordered over two sites with site occupancy factors 0.508 (12) and 0.492 (12). The methyl group of the acetate ligand is disordered over two positions of equal occupancy (0.5:0.5).

Experimental top

A mixture of AgNO3(0.057 g, 0.33 mmol), Dy2O3(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 then slowly cooled to room temperature. The product was collected by filtration, washed with water and air-dried. Colorless block 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 = 0.82 Å. The perchlorate anion is disordered over two sites with site occupancy factors 0.508 (12) and 0.492 (12). The methyl group of the acetate ligand is disordered over two positions of equal occupancy (0.5:0.5).

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.
