Carbonyl halides of the Group VI transition metals. XIV. Substitution derivatives of the trihalotetracarbonylmolybdenum(II) anions

Abstract

The complete series of substituted halocarbonyl anions [Mo(CO)₃RPh₃X₃]^- (where R is P, Sb, As; X is Cl, Br) have been characterized as their tetraethyl-ammonium salts. Each substituted anion has been prepared by two distinct methods and all of the compounds can exist as two isomers. Except for the α-isomer of [Mo(CO)₃PPh₃Br₃]^- these complexes are reported for the first time.
