文摘

Four copper(I) coordination polymers (CPs), {[CuIL]路CH₃CN]}_n (1), {[CuIL]路CHCl₃}_n (2), {[CuIL]路CH₂Cl₂}_n (3), and [CuIL]_n (4), were prepared by self-assembly reactions between CuI and (2-pyrazinylcarbonyl)thiomorpholine (L). CPs 1鈥?b>4 are interconnected by rhomboid Cu鈥揑₂鈥揅u units. CPs 1 and 4 have one-dimensional loop-chain structures, and 2 and 3 adopt two-dimensional network structures. CPs 1鈥?b>4 are pseudopolymorphic supramolecular isomers. CPs 2鈥?and 3鈥?are prepared by removal of solvate molecules from CPs 2 and 3, which are polymorphic supramolecular isomers with CP 4. Reversible crystal-to-crystal transformations were observed under appropriate conditions such as solvent or heat.
