Abstract
- Abstract: A new complex, [Pb2(H2O)2(HBTC)2]·3H2O (H3BTC=1,3,5-Benzenetricarboxylic acid) (1), has been synthesized under hydrothermal condition. The single-crystal analysis shows that 1 consists of 1-D double-chains with Pb(II) six-coordinated by three H3BTC and one H2O molecule with the Pb–O bond distances in the range of 2.56–2.76Å. When the Pb–O bonding limit extends from 2.76 to 2.90Å, the potential weak bonds of Pb–O can be found and the coordination number of Pb will increase from six to nine. As a result, the coordination geometry of Pb(II) transforms from hemidirected to holodirected and an infinite 3-D framework is obtained by the connection of the double-chains. The IR spectrum and the TGA–DTA curve of 1 are also reported in this paper. [Copyright &y& Elsevier]
