“…These results indicate unambiguously water as the source of O atoms in the cluster core. With a reference to our previous work [4] we found that in the reaction of ReI 3 with 3-methylpyridine in the presence of water the crystalline [Re 6 (l-O) 12 (3-Mepy) 6 ]I (2) complex can be isolated, which is subsequently readily converted to [Re 6 (l-O) 12 (3-Mepy) 6 ]BPh 4 . The complex 2 can be obtained in the two polymorphous forms: cubic (2a) (site symmetry 43m (Td)), when it is crystallized from CH 3 CN and trigonal 2b (site symmetry 3(C 3i )), when crystallized from CHCl 3 .…”

The {Re₄} Tetrahedral Cyanometalate Cluster Anion [{Re₄(μ₃-CCN)₄}(CN)₁₂]^8– with Inner (μ₃-CCN)^3– Ligands and Its Features in Coordination of Cu²⁺ Cations

A reaction between ReI 3 and KCN at elevated temperature led to the formation of the new cyanometalate cluster anion [{Re 4 (μ 3 -CCN) 4 }(CN) 12 ] 8− (1). The anion contains μ 3 -CCN 3− ligands, which are stabilized by the coordination to the triangular faces of the tetrahedral {Re 4 } metallocluster in a μ 3 mode. The compound crystallized as a potassium salt, and its crystal structure was determined by single-crystal X-ray diffraction analysis. It was shown that μ 3 -CCN 3− ligands are ambidentate and can interact with transition-metal cations similarly to terminal CN groups, resulting in the polymer framework formation.

The interaction of rhenium(III) halides Re 3 Br 9 and Re 3 I 9 with aqueous solution of sodium cyanide resulted in the formation of the first trinuclear halide−cyanide rhenium cluster complexes [{Re 3 X 3 }(CN) 9 ] 5− /[{Re 3 X 3 }(CN) 9 ] 4− (X = Br or I) crystallized as salts of the compositions Cs 4 Na[{Re 3 Br 3 }(CN 3), and Cs 4 [{Re 3 I 3 }(CN) 9 ]•(4). All of the compounds are stable in air in the solid state and in aqueous solution. The substitution of apical halide ligands in the parent compounds Re 3 X 9 by cyanides led to reduction of the original metallocluster Re 3 9+ (12 cluster valence electrons (CVEs)) to Re 3 7+ (14 CVEs), forming the compounds 1 and 2. The apical CN − ligands affect the electronic structure of the Re 3 metallocluster stabilizing reduced form. Complexes 1 and 2 represent the first examples of triangular rhenium clusters with the Re 3 7+ metallocluster. The reaction of 1 and 2 with H 2 O 2 resulted in formation of compounds 3 and 4 with the formal charge of the Re 3 metallocluster equal to 8+, and no further oxidation to Re 3 9+ occurred. The compounds were characterized by the X-ray diffraction analysis, NMR and UV−vis spectroscopies, mass spectrometry, cyclic voltammetry, and magnetic susceptibility measurements.
