Abstract top

The title mixed-metal complex, {(NH4)2[Cu(C7H3NO4)2(H2O)2][CdCu(C7H3NO4)2(H2O)6]·6H2O}n, contains one octahedrally coordinated CdII center and two octahedrally coordinated CuII centers, each lying on an inversion center. The two CuII atoms are each coordinated by two O atoms and two N atoms from two 2,4-pydc (2,4-H2pydc = pyridine-2,4-dicarboxylic acid) ligands in the equatorial plane and two water molecules at the axial sites, thus producing two crystallographically independent [Cu(2,4-pydc)2(H2O)2]2- metalloligands. One metalloligand exists as a discrete anion and the other connects the Cd(H2O)4 units, forming a neutral chain. O-H...O and N-H...O hydrogen bonds connects the polymeric chains, complex anions, ammonium cations and uncoordinated water molecules into a three-dimensional supramolecular network.

Comment top

Coordination polymers constructed from metal ions and bridging ligands have been of great interest owing to their structural diversities and fascinating properties (Caneschi et al., 2001; Evans & Lin, 2002; Kitagawa et al., 1999, 2004). In recent years, the design and synthesis of mixed-metal coordination polymers have received much attention because such heterometallic materials might exhibit interesting physical properties, resulting from interactions between two neighboring metal centers connected by a suitable linker (Dong et al., 2000; Kitagawa et al., 2006). Noro et al. (2002a, b) have prepared mixed-metal coordination polymers by using the Et3NH salt of a metalloligand, [Cu(2,4-pydc)2]2- (2,4-H2pydc = pyridine-2,4-dicarboxylic acid). We prepared recently a mixed-metal complex with a metalloligand [Cu(2,5-pydc)2]2- by a simplified synthetic method (Wang et al., 2009). As a continuation of our work, we report here the synthesis and structure of the title compound.

The asymmetric unit of the title compound contains one six-coordinated CdII atom and two six-coordinated CuII atoms, each lying on an inversion center, two 2,4-pydc ligands, one ammonium ion, four coordinated water molecules and three uncoordinated water molecules (Fig. 1). Both Cu1 and Cu2 atoms have an axially elongated octahedral coordination geometry, defined by two O atoms and two N atoms from two 2,4-pydc ligands in the equatorial plane and two water molecules at the axial sites, thus producing two crystallographically independent [Cu(2,4-pydc)2(H2O)2]2- metalloligands. In each metalloligand, the equatorial plane consists of trans N donors and trans O donors. The CdII ions coordinated by four water molecules are linked by the Cu1-metalloligands, via the bidentate-bridging 2-carboxylate groups, into a one-dimensional polymeric chain along the [100] direction (Fig. 2). The shortest Cu···Cd distance is 5.226 (1) Å. The 2,4-pydc ligand binds Cu1 and Cd1 atoms in a µ2-(κ3N,O2:O2') mode with the 4-carboxylate group uncoordinated (Li et al., 2008). The Cu2-metalloligand acts as a discrete divalent anion and does not interact with a second metal ion. The 2,4-pydc ligand in the Cu2-metalloligand adopts a (κ2N,O2) chelating mode with the 4-carboxylate group remaining idle. Extensive O—H···O and N—H···O hydrogen bonds (Table 1) assemble the various components into a supramolecular network (Fig. 3).

Experimental top

An aqueous solution (20 ml) of Cu(NO3)2.3H2O (0.125 g, 0.3 mmol) and a suspension of 2,4-H2pydc (0.083 g, 0.3 mmol) in ethanol (10 ml) were mixed and refluxed for 24 h until a clear solution was obtained. To this solution, an aqueous solution (5 ml) of CdCl2 (0.055 g, 0.5 mmol) was added. Aqueous NH3 (25%, 0.06 ml) was then slowly added to the reaction mixture. The resulting solution was filtered off. Blue block crystals were obtained by allowing the filtrate to stand at room temperature for several days.

Refinement top

H atoms on C atoms were positioned geometrically and refined using a riding model, with C—H = 0.93 Å and with Uiso(H) = 1.2Ueq(C). H atoms of water molecules and ammonium ion were located in a difference Fourier map and refined with distance restraints of O—H = 0.96 (1), H···H = 1.56 (1) Å, and N—H = 0.99 (1), H···H = 1.62 (1) Å, and with Uiso(H) = 1.2Ueq(O,N).
