Abstract

The X-ray crystal structure of the complex [Pd(tu)4]I2 (tu = thiourea) is reported. This complex crystallizes in the monoclinic space group C2/c with cell parameters a = 16.430(2), b = 9.060(2), c = 13.504(2) Å, β = 114.45(2)°. The structure model, with all non-H atoms anisotropic, was refined to R = 0.028 and Rw = 0.031, with the goodness-of-fit (S) = 0.91. The structure of the compound consists of Pdtu42+ cations and uncoordinated iodide anions. The Pd(II) atoms are linked to sulfur atoms of tu in a square planar arrangement.
