Poly[[{mu(4)-3-[(1H-1,2,4-triazol-1-yl)methyl]benzoato}zinc(II)] hemihydrate]: a novel two-dimensional framework formed by self-association of zinc(II) sulfate with 3-[(1H-1,2,4-triazol-1-yl)methyl]benzoic acid.
The title novel two-dimensional coordination polymer, {[Zn(2)(C(10)H(8)N(3)O(2))(4)].H(2)O}(n), features a {Zn(2)L(2)} bimetallic ring repeat unit {L is the 3-[(1H-1,2,4-triazol-1-yl)methyl]benzoate ligand}. Each Zn(II) cation of the bimetallic ring is further bonded to two other L ligands, resulting in a novel infinite two-dimensional network structure with two channels of different sizes. The crystallographically unique Zn(II) atom is thus six-coordinated in a distorted octahedral environment of four carboxylate O atoms and two triazole N atoms. Two of these networks interpenetrate in an orthogonal arrangement to form the full three-dimensional framework, with disordered water molecules located in the channels.
