Abstract

The title compound was obtained by arc melting of the elemental components and subsequent annealing in a high frequency furnace. It crystallizes with the orthorhombic space group Cmmm, a = 779.26(7) pm, b = 1362.0(1) pm, c = 320.62(3) pm, V = 0.3403 nm3, Z = 2. The structure was determined from single-crystal X-ray data and refined to a residual of R = 0.021 (692 F values and 21 variables). It is closely related to the NaCl-structure. Three of the seven carbon atoms per formula unit form linear C3 -units with C-C bond lengths of 134 pm. They are coordinated to ten Sc atoms forming bicapped quadratic prisms. Additional isolated C atoms are located in octahedral voids formed by four Sc and two Re atoms. Together with the Re atoms they form two-dimensionally infinite [Re2C411-]n polyanions. The Re atoms have highly distorted tetrahedral carbon coordination with Re -C bond lengths of 200 and 208 pm corresponding to bond orders of about two. This coordination seems to be compatible with the 18-electron rule. The near-neighbour coordination of the Re atoms is assymmetric. It is suggested that this is due to the space requirements of nonbonding electrons. Samples of Sc5Re2C7 are semiconducting and weakly paramagnetic.

Keywords: Crystal Structure; Scandium Rhenium Carbide; 18-Electron Rule
