Hydrothermal Synthesis and Crystal Structure of (4,4'-H2bipy)(ZnI4)

Abstract

(4,4'-H₂bipy)(ZnI₄) (1) has been synthesized via hydrothermal reaction and characterized by single crystal X-ray diffraction. The crystal belongs to monoclinic, space group P2₁/c with a = 7.7756(6), b = 21.536(2), c = 10.9188(8) Å, β = 106.606(1)º, C₁₀H₁₀N₂I₄Zn, Mr = 731.17, V = 1752.1(2) ų, Z = 4, D_c = 2.772 g/cm³, S = 1.002, μ(MoK_α) = 8.433 mm^-1, F(000) = 1304, R = 0.0239 and wR = 0.0544. The crystal structure analysis of (4,4'-H₂bipy)(ZnI₄) shows that this compound features an isolated structure, based on discrete 4,4'-H₂bipy moieties and tetrahedral zinc atoms terminally coordinated by four iodine atoms. The 4,4'-H₂bipy and ZnI₄ moieties are interconnected by hydrogen bonds to yield a 1-D supramolecular chain.
