摘要：

Two new diperoxo complexes of niobium using 8-quinolinolate (Q) as the ligand, K[NbOH(O(2))(2)Q]. 2H(2)O (1) and K[Nb(O(2))(2)Q(2)]. 3H(2)O (2), have been synthesised and characterised structurally by elemental analysis, IR and NMR ((1)H, (13)C, (93)Nb) spectroscopy. The (1)H and (13)C NMR signals of the free ligand undergo shift on complexation. (C) 2001 Elsevier Science Ltd. All rights reserved.
