Chlorotris(N,N'-dicyclohexylthiourea-S)tellurium(II) chloride, a tellurium complex with a TeClS3 coordination sphere.
During the synthesis of a series of square-planar [TeCl2(stu)2] complexes, where stu represents bulky di- or tetrasubstituted thioureas, the title compound, [TeCl[(C6H11NH)2CS]3]Cl or C39H72ClN6S3Te+*Cl-, was the unexpected result when stu was N,N'-dicyclohexylthiourea. The complex is square planar, with Te-S distances of 2.5803 (4), 2.6211 (4) and 2.8214 (4) A, and a Te-Cl distance of 2.6485 (4) A, indicating a small trans influence of the thiourea ligand.
