摘要:
The hydrothermal reactions of CUSO4 - 5H(2)O, a phosphonate ligand and an appropriate aromatic nitrogen heterocycle yield a series of materials of the Cu(II)/phosphonate/nitrogen ligand donor family. Two of the materials [Cu(2,2'-bpy)(HO3PCH2CH2CH2PO3H)] (1) and [Cu(4,4'-bpy)(H2O)(2)(HO3PCH2CH2CH2CH2PO3H)] (2) are two-dimensional, while [{Cu(2,2'-bpy)}(2)(O3PC6H4PO3)](.) 8H(2)O (3 (.) 8H(2)O) is three-dimensional. When 1,3,5-benzenetricarboxylic acid is introduced as a reactant, the one-dimensional material [Cu(2,2'-bpy){OC6H2(CO2H)(3)} (HOPC6H5)] (4) is isolated. This is an example of an in situ hydrothermal ligand transformation in which the 1,3,5-benzene tricarboxylic acid is hydroxylated to give 1,3,5-benzene tricarboxylic acid-2-hydroxide. Compound 5 [Cu(terpy)(HO3PC6H4PO3H] is molecular. (c) 2006 Elsevier B.V. All rights reserved.
