In the isostructural title complexes, [M(C9H6N3O2)2(H2O)2] [M = Co II, (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 carboxyl-ate groups and by two trans-coordinated aqua ligands, forming a distorted octa-hedral environment. The mol-ecules 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 inter-actions; O...N = 2.749 (3)-2.872 (3) A]. The layers are parallel and are tightly packed with short inter-layer distances of 4.93, 4.95 and 5.01 A for (I), (II) and (III), respectively. International Union of Crystallography 2007.

Hydrogen-bonded supramolecular frameworks remain highly interesting for the development of novel porous materials. Herein a hydrogen-bonded supramolecular framework of a cobalt(II) complex, [Co(cpt)2(H2O)2] (Hcpt = 4-(p-carboxyphenyl)-1,2,4-triazole), was synthesized and structurally characterized. A single crystal X-ray diffraction (SC-XRD) study indicates that the monometallic Co2+ ion is located in a distorted octahedral geometry and the complex forms a two-dimensional supramolecular network stabilised by significant intermolecular N···H interactions. Variable-temperature PXRD and TGA analysis experiments revealed considerable thermal stability of the supramolecular framework of the CoII complex. Magnetic studies showed that the distorted octahedral Co2+ ion exhibits considerable easy-plane magnetic anisotropy with D = 22.3 cm?1, while field-induced single-ion magnet (SIM) behavior was evidenced at low temperature. The forgoing results further highlight that the hydrogen-bonded supramolecular framework could be used as a great platform for the development of molecular nanomagnets.

Three new cpt-metal complexes of different topology structures were synthesized by solvothermal methods [Hcpt = 4-(4-carboxyphenyl)-1,2,4-triazole]. The structure of [Mn(cpt)2·2H2O] (1) is essentially 0D monomeric, but extended into
