Heterobimetallic heterocyclic derivatives of indium(III)

Reactions of InCl3 with potassium salts of bifunctional tridentate (L1H2HOC6H4CH NCH2CHMeOH) and monofunctional bidentate (L2HHOC6H4CHN-i-Bu) Schiff bases in 1:1 and 1:2 molar ratio in benzene afford complexes In(L1)Cl and In(L2)2Cl, respectively. On reaction with potassium isopropoxymetallates KB(O-i-Pr)4, KAl(O-i-Pr)4, KTi(O-i-Pr)5, and KNb(O-i-Pr)6, they produce interes- ting heterobimetallic heterocyclic complexes. These are characterized by elemental (N, B, Al, Ti, and Nb) analyses, molecular weight measurements, and spectral [IR, NMR (1H, 13C, 11B, and 27Al)] studies. Probable structures are suggested for them. © 2003 Wiley Periodicals, Inc. 15:21–25, 2004; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/.hc10206
