Abstract

A series of heterometallic tetrahedral cluster complexes with the general formula [{MxRe4−xSe4}(CN)12]n− (M = Mo, W; x = 2, 3) were obtained using the reaction of ReI3 and MO3 with selenium and KCN at elevated temperatures. Compounds [ReW3Se4(CN)12]6− and [Re2W2Se4(CN)12]6− are the first rhenium–tungsten heterometallic clusters. Crystal structures, electrochemical properties in aqueous solutions and magnetic properties of crystalline samples have been studied in detail. It has been shown that new cluster anions demonstrate a regular change in geometric characteristics and redox potentials depending on the composition of the cluster core.

Abstract

By a high-temperature reaction of rhenium(III) iodide and red phosphorus with an excess of sodium cyanide followed by recrystallization from an aqueous solution a new tetrahedral [{Re4(PO)4}(CN)12]8– anionic cluster complex is obtained. It is isolated as a salt of the composition Na8[{Re4(PO)4}(CN)12] 18H2O·MeOH. The structure of the obtained compound is determined by X-ray crystallography. The compound crystallizes in the monoclinic crystal system, P21/n space group, unit cell parameters a = 26.826(3) A, b = 11.4975(12) A, c = 29.141(3) A, β = 97.879(2)°, V = 8903.2(16) A3, Z = 8.

Abstract

New tetrahedral anionic rhenium cluster complexes [{Re4(PO)3(PO2)}(CN)12]8- (1) and [{Re4As2(AsO)2}(CN)12]8- (2) have been synthesized by the reaction of ReI3 with NaCN and Pred or KCN and Asgray, respectively. Compound 2 was further oxidized by aqueous H2O2 to produce the cluster anion [{Re4(AsO)4}(CN)12]8- (3). The anions contain new pnictogen/oxygen-based ligands, PO23- and AsO3-, which were stabilized by the coordination to the triangular faces of the tetrahedral Re4 metallocluster in μ3-mode. All three compounds were crystallized as either sodium or potassium salts, and their crystal structures were determined by single crystal X-ray diffraction analysis.
