A simultaneous reduction, substitution, and self-assembly reaction under hydrothermal conditions afforded the first diiodopyridine copper(I) coordination polymer

A simultaneous reduction of copper(II) to copper(I) by pyridinecarboxylate and the substitution of carboxylato groups by iodo nucleophiles in a self-assembly process under hydrothermal conditions afforded a new iodine-inclusion coordination polymer [CuI(C(5)H(3)NI(2)).(1)/(2)I(2)]. The synthetic studies of the substitution process produced a new supramolecular compound [IC(5)H(3)NCOOH] 2 and revealed that the catalytic properties of copper ions in redox and substitution reactions under hydrothermal conditions are attractive, Crystal data for [CuI(C(5)H(3)NI(2)).(1)/(2)I(2)]: triclinic, space group F; cell dimensions a = 4.216(1) Angstrom, b = 11.254(2) Angstrom, c = 12,196(2) Angstrom, alpha = 80.34(3)degrees, beta = 88.44(3)degrees, gamma = 83.10(3); V = 566.2(2) Angstrom(3), Z = 2.
