ABSTRACT
The title complexes, hexaaquacobalt(II) bis(µ-pyridine-2,6-dicarboxylato)bis[(pyridine-2,6-dicarboxylato)bismuthate(III)] dihydrate, [Co(H(2)O)(6)][Bi(2)(C(7)H(4)NO(4))(4)]·2H(2)O, (I), and hexaaquanickel(II) bis(µ-pyridine-2,6-dicarboxylato)bis[(pyridine-2,6-dicarboxylato)bismuthate(III)] dihydrate, [Ni(H(2)O)(6)][Bi(2)(C(7)H(4)NO(4))(4)]·2H(2)O, (II), are isomorphous and crystallize in the triclinic space group P-1. The transition metal ions are located on the inversion centre and adopt slightly distorted MO(6) (M = Co or Ni) octahedral geometries. Two [Bi(pydc)(2)](-) units (pydc is pyridine-2,6-dicarboxylate) are linked via bridging carboxylate groups into centrosymmetric [Bi(2)(pydc)(4)](2-) dianions. The crystal packing reveals that the [M(H(2)O)(6)](2+) cations, [Bi(2)(pydc)(4)](2-) anions and solvent water molecules form multiple hydrogen bonds to generate a supramolecular three-dimensional network. The formation of secondary Bi...O bonds between adjacent [Bi(2)(pydc)(4)](2-) dimers provides an additional supramolecular synthon that directs and facilitates the crystal packing of both (I) and (II).
