摘要
The crystal structures of [Co(II)(L)(NO3)(HOCH3)(n)]BPh4 {L = cis,cis-1,3,5-tri[(4-tert- butylphenyl)propenylideneamino]cyclohexane} complexes demonstrate the role of solvent molecules in the stabilisation of anions within a solvated cavity: the structures can be compared with bicarbonate binding in the active site of carbonic anhydrase.
