Abstract

The trianion Z3- obtained from 9-phenyl 2,3,7-trihydroxyfluor-6- one, ZH3, affords dioxomolybdenum and dioxotungsten derivatives which contain [4 + 4] metallocycles of composition [(MO2) 4Z4]4- (M = Mo, W) in combination with a variety of counter cations. The syntheses, structures and ESMS of the following compounds are presented: compound 1, (MePPh3)3(NBu 4)[(MoO2)4Z4]; compound 2, (MePPh3)3(NBu4)[(WO2) 4Z4]; compound 3, (MePPh3)4[(WO 2)4Z4]; compound 4, (PPh4) 2(NBu4)2[(MoO2)4Z 4]; compound 5, (AsPh4)3(NBu 4)[(MoO2)4Z4]; compound 6, (AsPh4)2(NBu4)2[(WO 2)4Z4]; compound 7, (Ph3PNPPh 3)(NBu4)3[(MoO2)4Z 4]; compound 8, (Ph3PNPPh3)(NBu 4)3[(WO2)4Z4]; compound 9, (NEt4)(NBu4)3[(MoO2) 4Z4].
