Description
| - To study the conformations of 1,2,3,4,5,6-cyclohexanehexacarboxylic acid (H6L), eleven new coordination polymers have been isolated from hydrothermal reactions of different metal salts with 1e,2a,3e,4a,5e,6a-cyclohexanehexacarboxylic acid (3e+3a, H6LI) and characterized. They are [Cd12(6-LII)(10-LII)3(-H2O)6(H2O)6]16.5 H2O (1), Na12[Cd6(6-LII)(6-LIII)3]27 H2O (2), [Cd3(13-LII)(-H2O)] (3), [Cd3(6-LIII)(2,2-bpy)3(H2O)3]2 H2O (4), [Cd4(4-LVI)2(4,4-Hbpy)4(4,4-bpy)2(H2O)4]9.5 H2O (5), [Cd2(6-LII)(4,4-Hbpy)2(H2O)10]5 H2O (6), [Cd3(11-LVI)(H2O)3] (7), [M3(9-LII)(H2O)6] (M=Mn (8), Fe (9), and Ni (10)), and [Ni4(OH)2(10-LII)(4,4-bpy)(H2O)4]6 H2O (11). Three new conformations of 1,2,3,4,5,6-cyclohexanehexacarboxylate, 6e (LII), 4e+2a (LIII) and 5e+1a (LVI), have been derived from the conformational conversions of LI and trapped in these complexes by controlling the conditions of the hydrothermal systems. Complexes 1 and 2 have three-dimensional (3D) coordination frameworks with nanoscale cages and are obtained
