dc.description.abstract	A variety of methods were investigated for the preparation of Nb6Cl14•8H2O. This hydrate is the starting material for the synthesis of coordination compounds based on hexanuclear {Nb6Cl12 )n+ central cations. Previous methods for its preparation were cumbersome, required expensive equipment, or supplied the hydrate only in small quantities. An efficient and convenient method for the synthesis of Nb6Cl14•8H20 was developed. Conproportionation of niobium pentachloride with excess niobium metal and with sodium chloride in sealed Vycor tubes supplies the ternary halide Na4Nb6Cl18. Upon extraction with water, Nb6Cl14•8H2O is obtained in yields up to 92%. The new coordination compounds [(Nb6Cl12)Cl2 (C5H5N)4] ·1.5(C5H5N), [(Nb6Cl12)Cl2(C2H5CN)4], and [(CH3)4N]2 [(Nb6Cl12)Br6] were synthesized and characterized.	en_US
