摘要：
The hydrothermal reaction of 2,5-pyridinedicarboxylic acid (H2PDC), diethylene triamine and In(NO3)(3)center dot 4.5H(2)O gave rise to a two-dimensional (2D) coordination polymer In(OH)(2,5-PDC). This compound crystallizes in the orthorhombic space group Iba2, with cell parameters, a = 12.656(3) angstrom, b = 20.114(4) angstrom, c = 6.2216(1) angstrom, V= 1583.9(5) angstrom(3) and Z = 8. Its structure contains one-dimensional In-O-In-O- chains, which are further linked by 2,5-PDC ligands into a 2D supramolecular neutral framework. The adjacent 2D layers are parallel with each other and construct a three-dimensional framework via hydrogen bands. At room temperature, the compound exhibits intense photoluminescence. On the basis of the results of TG/DTA analyses, the structure is thermally stable up to similar to 390 degrees C. (c) 2006 Elsevier B.V. All rights reserved.
