Abstract

Interesting varieties of heterobimetallic mixed-ligand complexes [Zr{M(OPri) n }2 (L)] (where M = Al, n = 4, L = OC6H4CH = NCH2CH2O (1); M = Nb, n = 6, L = OC6H4CH = NCH2CH2O (2); M = Al, n = 4, L = OC10H6CH = NCH2CH2O (3); M = Nb, n = 6, L = OC10H6CH = NCH2CH2O (4)), [Zr{Al(OPri)4}2Cl(OAr)] (where Ar = C6H3Me2-2,5 (5); Ar = C6H2Me-4-Bu2-2,6 (6), [Zr{Al(OPri)4}2(OAr)2] (where Ar = C6H3Me2-2,5 (7); Ar = C6H2Me-4-Bu2-2,6 (8), [Zr{Al(OPri)4}3(OAr)] (where Ar = C6H3Me2-2,5 (9); Ar = C6H3Me2-2,6 (10), [ZrAl(OPri)7-n (ON=CMe2) n ] (where n = 4 (11); n = 7 (12), [ZrAl2(OPri)10-n (ON=CMe2) n ] (where n = 4 (13); n = 6 (14); n = 10 (15) and [Zr{Al(OPri)4}2{ON=CMe(R)} n Cl2–n] [where n = 1, R = Me (16); n = 2, R = Me (17); n = 1, R = Et (18); n = 2, R = Et (19)] have been prepared either by the salt elimination method or by alkoxide-ligand exchange. All of these heterobimetallic complexes have been characterized by elemental analyses, molecular weight measurements, and spectroscopic (I.r., 1H-, and 27Al- n.m.r.) studies.
