Two new metal coordination polymers containing mixed ligands: hydrothermal synthesis and crystal structures of [Co_2(1,2,4,5-btc)(phen)_2(H_2O)_6] 2H_2O and [mn_3(1,2,4-bte)_2(phen)_2(H_2O)_2]_n

摘要

Crystallisation of benzene-1,2,4,5-tetracarboxylic acid or benzene-1,2,4-tricarboxylic acid with divalent metal ions of Co, and Mn with 1,10-phenanthroline gives two new coordination solids, [Co_2(C_(10)H_2O_8)(C_(12)H_8N_2)_2(H_2O)_6]-2H_2O (1) and [Mn_3(C_9H_3O_6)2(C_(12)H_8N_2)_2(H_2O)_2], (2). The three-dimensional supramolecular structure of compound 1 is constructed from discrete [Co_2(C_(10)H_2O_8)(C_(12)H_8N_2)_2(OH_2)s] dimers and isolated water molecules via interesting hydrogen-bonding and pai~pai stacking interactions. Compound 2 has an unusual (4,6) network, and the network is furthermore extended into a three-dimensional supramolecular architecture by the aid of hydrogen bonding and pai-pai stacking interactions.
