Guest-induced Single-crystal-to-single-crystal Transformation in Copper Complexes of 1,3,5-Benzenetricarboxylic Acid and 4,4'-Bipyridine
A 2-dimensional (2D) noninterpenetrated flexible porous coordination polymer, [Cu(HBTC)(4,4'-bpy)] C6H11OH H2O (1), has been synthesized and characterized using single-crystal X-ray diffraction The cyclohexanol guest molecules in 1 can be removed upon soaking 1 in ethanol Complex 1 undergoes a single-crystal transformation to form an ethanol solvate, [Cu(HBTC)(4,4'-bpy)(H2O)] C2H5OH 2H(2)O (2), and during the process, the octahedral coordination of the copper cation in 1 converts to square-pyramidal coordination in 2
