Abstract The reactions of NbCl 3 with Me 3 SiOMe in the appropriate molar ratios have given new alkoxoniobium (V) derivatives of the type NbCl 5− x (OMe) x (x= 2 (I), 3 (II)). Reactions of I and II with various ligands afford the corresponding species NbCl 5− x (OMe) x L, x= 2, L= OPPh 3 (III); L= OAsPh 3 (IV); L= THF (V); L= Cl−(VI); x= 3, L= OPPh 3 (VII); L= Cl−(VIII). Similar hexacoordinate compounds NbCl 3 (OR) 2 (OPPh 3),(R= Me (III), R= Et (IX), R= Pr ...
