2O,O']cobalt(II), and the cadmium(II) and copper(II) analogues: new self-complementary hydrogen-bond donor/acceptor modules for designing hydrogen-bonded frameworksAbstract: In the isostructural title complexes, [M(C9H6N3O2)2(H2O)2] [M = CoII, (I), CdII, (II), and CuII, (III); the metal centres reside on a twofold axis in the space group C2/c for (I) and (II)], the metal centres are surrounded by four O atoms from two O,O'-bidentate carboxylate groups and by two trans-coordinated aqua ligands, forming a distorted octahedral environment. The molecules possess four hydrogen-bond donor (two aqua ligands) and four hydrogen-bond acceptor sites (two triazole groups), and aggregate by self-association, forming two-dimensional hydrogen-bonded frameworks [via O-H
N interactions; ON = 2.749 (3)-2.872 (3) Å]. The layers are parallel and are tightly packed with short interlayer distances of 4.93, 4.95 and 5.01 Å for (I), (II) and (III), respectively.
Formula: [Co(C9H6N3O2)2(H2O)2], [Cd(C9H6N3O2)2(H2O)2] and [Cu(C9H6N3O2)2(H2O)2]
