1-D coordination polymers containing benzenedicarboxylate

Abstract

The preparation and crystal structures of [Cu(1,3-bdc)(py) 3].1 1 2 H 2O ( 1), [Cu(1,3-bdc)(py) 3].H 2O.CH 3OH ( 2), [Co(1,3-bdc)(py) 3(H 2O)] ( 3), [Co(1,3-bdc)(py) 3(CH 3OH)].H 2O ( 4), [Cu(1,3-bdc)(py) 2] ( 5), [Co(1,3-bdc)(CH 3OH) 4] ( 6) and [Ni(1,3-bdc)(CH 3OH) 4] ( 7) are described (1,3-bdc=1,3-benzenedicarboxylic acid; py=pyridine). 1– 4 form straight-chain 1-D coordination polymers with interdigitated pyridyl ligands that are engaged in C-H···π hydrogen bonds. 6 and 7 form similar 1-D polymeric chains, but the smaller methanol ligands allow the bdc groups to stack to form π···π interactions. 5 forms a rectangular 2-D grid structure with insufficient space for guest inclusion.
