Reactions of Sulphaguanidine with Chlorides and Bromides of Niobium (V) and Tantalum (V)

R. N. Pandey and Kalpana Shahi

Reaction of sulphaguanidine with chlorides and bromides of Niobium (V) and Tantalum (V) yields seven coordinated solid complexes of composition [MX5L] (M = Nb/Ta; X = Cl/Br; L = Sulphaguanidine). The reaction products have been characterized by elemental analyses, magnetic measurements, conductivity, IR, UV-vis spectral studies. Sulphaguanidine behaves as neutral bidentate N, O-donor.
