A mixture of CuO (0.082 g, 1.0 mmol), Dy2O3 (0.181 g, 0.5 mmol), isonicotinic acid (0.248 g, 2.0 mmol), H2O (10 ml, 0.55 mmol) and two drops of acetic acid, with a pH value about 2.0, was sealed in a 25 ml Teflon-lined reaction vessel at 443 K for 5 d. The reaction mixture was cooled to room temperature over a period of 48 h. The product was collected by filtration, washed with water and air-dried. Blue block crystals suitable for X-ray analysis were obtained. Analysis, calculated for C48H40CuDy2N8O20: C 40.11, H 2.80, N 7.80%; found: C 40.05; H 2.59, N 7.97%.
H atoms bonded to C atoms were positioned geometrically and refined as riding, with C—H = 0.93Å and Uiso(H) = 1.2Ueq(C). H atoms of water molecules were found from difference Fourier maps and refined isotropically with a restraint of O—H = 0.82 (1) Å.
In the past few years, more extensive attention had been paid to the research on the chemistry of heterometallic complexes containing simultaneously lanthanide and transition metal ions (Costs et al., 1998; Kahn et al., 1999; Sanz et al., 1996). As an extension of this research, we report here the structure of the title compound, a new heterometallic coordination polymer,
In the title compound (Fig. 1), the CuII atom lies on an inversion center and is six-coordinated by two O atoms from two monodentate isonicotinate ligands and four N atoms from the other four isonicotinate ligands. Thus the CuII atom has a slight distorted octahedral coordination geometry. The DyIII atom is eight-coordinated by six O atoms from five different isonicotinate ligands and two O atoms from two water molecules in a square antiprism geometry (Table 1). The adjacent Cu and Dy coordination units are bridged by the tridentate isonicotinate ligands, forming a three-dimensional network structure (Fig. 2).

In the past few years, more extensive attention had been paid to the research on the chemistry of heterometallic complexes containing simultaneously lanthanide and transition metal ions (Costs et al., 1998; Kahn et al., 1999; Sanz et al., 1996). As an extension of this research, we report here the structure of the title compound, a new heterometallic coordination polymer,
In the title compound (Fig. 1), the CuII atom lies on an inversion center and is six-coordinated by two O atoms from two monodentate isonicotinate ligands and four N atoms from the other four isonicotinate ligands. Thus the CuII atom has a slight distorted octahedral coordination geometry. The DyIII atom is eight-coordinated by six O atoms from five different isonicotinate ligands and two O atoms from two water molecules in a square antiprism geometry (Table 1). The adjacent Cu and Dy coordination units are bridged by the tridentate isonicotinate ligands, forming a three-dimensional network structure (Fig. 2).
