The reaction of lacunary polyanion [alpha-H(2)P(2)W(12)O(48)](12-), zinc acetate, bpp (1,3-bis(4-pyridyl) propane) and BTC (1,3,5-benzenetricarboxylate) in an acidic aqueous solution led to the isolation of a new complex [Zn(3)(BTC)(2)(chtpy)(H(2)O)(2)] center dot 2H(2)O (1), which crystallizes in the space group C2/c with a = 28.988(6) angstrom, b = 11.254(2) angstrom, c = 17.347(4) angstrom, V = 4682.5(2) angstrom(3), Z = 4. X-ray diffraction analysis reveals that there exists the generation of in situ ligand through simultaneous dehydrogenative coupling and hydroxylation of an N-heterocyclic ligand in complex 1. More interestingly, it exhibits an unprecedented (3,4)-connected (8(2).10)(2)(8(3))(2)(8(4).10.12)(8(5).10) topology which has been reported for the first time and shows self-penetrating nature at the same time.
