Abstract
Reaction between rhenium(III) chloride and 4, 6-dimethylpyrimidine-2(lH)-thione hydrochloride in concentrated HC1 solution results in the formation of [Re3Cl9(H2O)3].2(C6H7N2S.HCl).- 2H20. The compound crystallizes in the orthorhombic space group Pnma with cell dimensions a 16·797(4), b 21·917(4), c 9·514(1) A and Z 4. The structure was solved by the heavy-atom method and refined by least-squares calculations to a final R value of 0·0517 (R'0·0602). The structure consists of discrete [Re3Cl9(H20)3] units, protonated organic molecules, chloride ions, and water molecules. In the cluster three rhenium atoms are linked to form a triangle, with chlorine atoms bridging each pair of rheniums which present short Re-Re bonds [2·440(1), 2·433(1) and 2·444(1) A], Three water molecules in the equatorial plane and six chlorine atoms perpendicular to it (three above and three below) make the coordination around each rhenium distorted pentagonal bipyramidal. © 1987 ASEG.
