Crystal Water of Cadmium Acetate-Dependent Formation of One-Dimensional Channel Structure Based on 4,4′-bis(1-Imidazolyl)biphenyl

A novel metal-organic framework with one-dimensional channels {[Cd(3)(CH3COO)2(H2O)2] (CH3CN)x(CH3OH)y} (5), based on conformationally restricted linear 4,4′-bis(1-imidazolyl)biphenyl (3) and cadmium acetate dihydrate, has been synthesized. It crystallizes in the triclinic system, space group P1̅ with a = 5.6528(11) Å, b = 9.887(3) Å, c = 12.924(3) Å, and Z = 1. The experimental results demonstrate that coordinated crystal water molecules may play a key role in the formation of the metal-organic frameworks.
