摘要

Triply interpenetrating 3-dimensional nickel and cobalt coordination polymers, [M-3(2,6-NDC)(3)(bipy)(1.5)], were prepared from metal nitrate {M(NO3)(2).6H(2)O), 2,6-naphthalenedicarboxylic acid (2,6-NDCH2), and 4,4'-bipyridine (bipy) under hydrothermal (M = Ni) or water-benzene hydro(solvo)thermal (M = Co) conditions. Both polymers have the same secondary building units (SBUs) of paddle-wheels of the type [M-2(CO2R)(4)], which are composed of two metals and four di(monodentate) bridging carboxylates. On the other hand, the hydrothermal reaction of Co(NO3)(2).6H(2)O with 1,3-benzenedicarboxylic acid (1,3-BDCH2) and trans-1,2-bis(4-pyridyl)ethylene (bipyen) gave a 2-dimensional polymer [Co(1,3-BDC)(bipyen)]. The structures of all products were determined by X-ray diffraction. (C) 2003 Elsevier B.V. All rights reserved. [References: 26]
