Cd(ii) coordination polymers constructed from tris-pyridyl-tris-amide and polycarboxylic acid: synthesis, structures and sensing properties

Abstract

Reactions of N,N’,N”-tris(3-methylpyridyl)trimesic amide (L) and Cd(OAc)2·2H2O with various polycarboxylic acids afforded {[Cd2(L)(1,4-BDC)2(H2O)2]∙2H2O}n (1,4-H2BDC = benzene-1,4-dicarboxylic acid), 1, {[Cd(L)(4,4’-BDC)(H2O)]∙H2O)}n (4,4’-H2BDC = biphenyl-4,4’-dicarboxylic acid), 2, and {[Cd3(L)2(1,3,5-BTC)2(H2O)6]∙15H2O}n (1,3,5-H3BTC = benzene-1,3,5-tricarboxylic acid),...
