title: A zinc(II) metal-organic framework with a novel topology formed from 4,4',4''-nitrilotribenzoate and 4,4'-bipyridine ligands.
abstract: A metal-organic framework with a novel topology, poly[sesqui(μ2-4,4'-bipyridine)bis(dimethylformamide)bis(μ4-4,4',4''-nitrilotribenzoato)trizinc(II)], [Zn3(C21H12NO6)2(C10H8N2)1.5(C3H7NO)2]n, was obtained by the solvothermal method using 4,4',4''-nitrilotribenzoic acid and 4,4'-bipyridine (bipy). The structure, determined by single-crystal X-ray diffraction analysis, possesses three kinds of crystallographically independent Zn(II) cations, as well as binuclear Zn2(COO)4(bipy)2 paddle-wheel clusters, and can be reduced to a novel topology of a (3,3,6)-connected 3-nodal net, with the Schläfli symbol {5.6(2)}4{5(2).6}4{5(8).8(7)} according to the topological analysis.
