Abstract

The compound [(CH₃)C(NH₂)₂]₄ [Re₆Se₈(CN)₆] has been synthesized by the reaction at 200°C for 3 days of Re₄Te₄(TeCl₂)₄Cl₈, KSeCN, and NH4Cl in superheated acetonitrile. This compound crystallizes in the space group C2/c of the monoclinic system with four formula units in a cell of dimensions a = 20.3113(14) Å, b = 10.1332(7) Å, c = 19.9981(14) Å, β = 106.754(1)°, V = 3941.3(5) Å³ (T = 153 K). The [Re₆Se₈(CN)₆]^4- anion comprises an Re₆ octahedron face capped by μ₃-Se atoms, with each Re atom liganded by a CN group. The anions and cations are connected by an extensive network of hydrogen bonds. The conversion of a Re(IV) tetrahedral cluster to a Re(III) octahedral cluster appears to be unprecedented.
