摘要：

Hydrothermal reaction of the mixed thiolate-carboxylate-aromatic amine ligand, 6-mercaptonicotinic acid (6-mnaH(2)) with Co(II) and Ni(II) leads to two network coordination solids [M-9(6-mna)(8)(mu 3-O)(2)-(OH3)(2)(OH2)(6)] (M = Co, Ni), 1, and [M2Ni12(6-mna)(12)(mu(3)-OH)(2)(-)(OH2)(6)]center dot 8H(2)O (M = K, Rb, Cs), 2. These compounds are unusual for two reasons: they are thiolate-bridged networks and they are three-dimensional lattices which contain isolated metal clusters and chains. The magnetic behavior of these compounds has been studied, showing that 2 contains ferromagnetically coupled Ni-6 wheels.
