Crystal Structure of Diiodobis(1-(6-methylpyridine-2-yl)thiourea-kS)mercury(II)

Abstract

The structure of diiodobis(1-(6-methylpyridine-2-yl)thiourea-kS)mercury(II) was determined by X-ray crystallography. This complex crystallizes in the space group P2₁/c, with cell parameters a = 10.3151(7)Å, b = 16.8739(10)Å, c = 13.7609(7)Å, β = 113.614(4)°, Z = 4, and V = 2194.6(2)ų. The crystal structure was solved by direct methods and refined by full-matrix least-squares on F² to final values of R1 = 0.0381 and wR2 = 0.0666. Two molecules of 1-(6-methylpyridin-2-yl)thiourea are coordinated to the mercury ions through monodentate sulfur atoms which leads to the formation of a distorted tetrahedral environment complex.
