摘　　要：A three-dimensional coordination polymer,[Ni（Hbyip2-）（bix）0.5（H2O）]n,has been hydrothermally synthesized.Each Ni2＋ ion is five-coordinated by three carboxylate O atoms from three different 5-（benzoic acid-4-yldiazenyl）isophthalate（Hbyip2-） anions,one N atom from one 1,4-bis（imidazol-1-ylmethyl）benzene（bix） ligand and one O atom from an aqua ligand displaying a distorted square-pyramid.Each Ni atom is defined by three Hbyip2-anions and each Hbyip2-anion adopts a tris（mono-dentate） ligand coordinating to three Ni2＋ ions affording a 36-membered inorganic ring.These rings are further arranged into an undulated two-dimensional layer parallel to the（101） plane.Adjacent two-dimensional networks are linked by bix ligands into a three-dimensional {63,83}{63} framework with a large channel（ca.26.3 × 13.6） along the [100] direction.Each individual {63,83}{63} network interpenetrates with two others in a parallel fashion to generate a 3-fold interpenetrating network.A three-dimensional coordination polymer,[Ni（Hbyip2-）（bix）0.5（H2O）]n,has been hydrothermally synthesized.Each Ni2＋ ion is five-coordinated by three carboxylate O atoms from three different 5-（benzoic acid-4-yldiazenyl）isophthalate（Hbyip2-） anions,one N atom from one 1,4-bis（imidazol-1-ylmethyl）benzene（bix） ligand and one O atom from an aqua ligand displaying a distorted square-pyramid.Each Ni atom is defined by three Hbyip2-anions and each Hbyip2-anion adopts a tris（mono-dentate） ligand coordinating to three Ni2＋ ions affording a 36-membered inorganic ring.These rings are further arranged into an undulated two-dimensional layer parallel to the（101） plane.Adjacent two-dimensional networks are linked by bix ligands into a three-dimensional {63,83}{63} framework with a large channel（ca.26.3 × 13.6） along the [100] direction.Each individual {63,83}{63} network interpenetrates with two others in a parallel fashion to generate a 3-fold interpenetrating network.
