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. Since Ni2 + ions are 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 by a tris (mono-dentate) ligand coordinating to three Ni2 + ions affording a 36-membered inorganic ring. The 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.
