摘要：

Crystals of the title compounds, [Cu(C6H6N2O)(2)(H2O)(2)]Cl-2, (I), and [Cu(C6H6N2O)(2)(H2O)(2)]Br-2, (II), are isomorphic. The structures consist of centrosymmetric complex cations and separate chloride or bromide ions linked by hydrogen bonding. The pyridine-2-carboxamide molecules (C6H6N2O) are coordinated by the ring N and amide O atoms, forming the base of an elongated octahedron. Bond lengths in O and (II), respectively: short Cu-N of 1.960(1) and 1.965(2), Cu-O of 1.981(1) and 1.981(2), and axial Cu-H2O of 2.418(2) and 2.417 (3) Angstrom.
