A new one-dimensional Ni^II coordination polymer with a two-dimensional supra-molecular architecture.

ABSTRACT: A new one-dimensional Ni^II coordination polymer of 1,3,5-tris-(imidazol-1-ylmeth-yl)benzene, namely catena-poly[[aqua-(sulfato-?O)hemi(?-ethane-1,2-diol-?²O:O')[?₃-1,3,5-tris-(1H-imidazol-1-ylmeth-yl)benzene-?³N³,N^3',N^3'']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 Ni^II cation is coordinated by three N atoms of three different 1,3,5-tris-(imidazol-1-ylmeth-yl)benzene ligands, one O atom of an ethane-1,2-diol mol-ecule, by a sulfate anion and a water mol-ecule, forming a distorted octa-hedral NiN₃O₃ coordination geometry. The tripodal 1,3,5-tris-(imidazol-1-ylmeth-yl)benzene ligands link the Ni^II 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 mol-ecule and a second ethane-1,2-diol mol-ecule are non-coordinating and are linked to the coordinating sulfate ions via O-H?O hydrogen bonds.
