【 摘 要 】

A new one-dimensional NiII coordination polymer of 1,3,5-tris­(imidazol-1-ylmeth­yl)benzene, namely catena-poly[[aqua­(sulfato-κO)hemi(μ-ethane-1,2-diol-κ2O:O′)[μ3-1,3,5-tris­(1H-imidazol-1-ylmeth­yl)benzene-κ3N3,N3′,N3′′]nickel(II)] ethane-1,2-diol monosolvate monohydrate], {[Ni(SO4)(C18H18N6)(C2H6O2)0.5(H2O)]·C2H6O2·H2O}n, was synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The NiII cation is coordinated by three N atoms of three different 1,3,5-tris­(imidazol-1-ylmeth­yl)benzene ligands, one O atom of an ethane-1,2-diol mol­ecule, by a sulfate anion and a water mol­ecule, forming a distorted octa­hedral NiN3O3 coordination geometry. The tripodal 1,3,5-tris­(imidazol-1-ylmeth­yl)benzene ligands link the NiII cations, generating metal–organic chains running along the [100] direction. Adjacent chains are further connected by O—H⋯O hydrogen bonds, resulting in a two-dimensional supermolecular architecture running parallel to the (001) plane. Another water mol­ecule and a second ethane-1,2-diol mol­ecule are non-coordinatingand are linked to the coordinating sulfate ions via O—H⋯O hydrogen bonds.
