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 P (1) over bar with a = 5.6528(11) angstrom, b = 9.887(3) angstrom, c = 12.924(3) angstrom, 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.
