Abstract: | NEt4[Re3Cl10(H2O)2] · 2 H2O ( 1 ) was obtained from hydrochloric acid solutions of ReCl3 and tetraethylammonium chloride, NEt4Cl, by isothermal evaporation as dark red crystals. 1 crystallizes in the orthorhombic crystal system, space group Pnma, Z = 4, with a = 1838,7(2), b = 1456.9(1), c = 972.08(7) pm, Vm = 391.81(6) cm3 · mol?l. The crystal structure consists of [Re3Cl10(H2O)2]? anions that are arranged in the fashion of a hexagonal closest-packing of spheres. These are held together by partially disordered NEt4+ cations and are bound into a hydrogen bonding system with the crystal water. |
