Luminescence Property and Structure of a 3D Six- and Eight-Coordinative Cd(II) MOF Containing a [Na-2(H2O)(6)] Unit

摘要

The preparation, structural characterization, and luminescence investigation of a new six- and eight-coordinative Cd(II) metal-organic framework of formula {[Cd-3(bta)(2)][Na-2(H2O)(6)]}(n) (1) (H(4)bta=1,2,4,5-benzenetetracarboxylic acid) is reported. The 3D structure of 1 consists of bta-bridged trinuclear Cd(II) where six oxygen atoms of four ((1), (1),-(2)) and one ((2), (2),-(4)) carboxylic groups and eight oxygen atoms from four ((2), (2),-(4)) carboxylic groups complete the six coordination and eight coordination environments around Cd1 and Cd2, respectively, in which is entrapped with [Na-2(H2O)(6)] unit. Furthermore, the luminescence is also discussed.
