Title: Synthesis and structure of the [OsThio{sub 6}]Br{sub 3} . H{sub 2}O complex

Abstract

A complex of the composition [OsThio{sub 6}]Br{sub 3} . H{sub 2}O is synthesized by the reaction of H{sub 2}OsBr{sub 6} with thiourea in a 0.5 M HBr solution. The [OsThio{sub 6}]Br{sub 3} . H{sub 2}O complex is characterized using electronic absorption and infrared spectroscopy. The structure of the complex is determined by X-ray diffraction analysis. The crystals are orthorhombic with the unit cell parameters a = 20.510(4) A, b = 11.186(2) A, c = 11.892(2) A, space group Pccn, and Z = 4. The thiourea molecules are coordinated to the osmium atom through the sulfur atom. The osmium atom has an octahedral coordination. The Os-S distances fall in the range 2.39-2.40 A. The outersphere H{sub 2}O molecules and Br{sup -} anions are involved in hydrogen bonds with the NH{sub 2} groups of the thiourea molecules.
