Ligand Exchange Reactions, Dioxomolybdenum(VI) Complexes, Tridentate Diacidic Ligands, Crystal Structure Dioxomolybdenum(VI) complexes have been synthesized by ligand exchange reactions o f M o(CO)6, M o(NO)2(acac)2 and M o 0 2(acac)2 with tridentate diacidic ligands. X-ray structure analyses were performed on single crystals. The complexes salicylaldehyde-2-hydroxyanilato(2-)-triphenylphosphaneoxide-dioxomolybdenum(VI) (lb ) and 2,2'-dihydroxyazobenzenato(2-)-triphenylphosphaneoxide-dioxomolybdenum(VI) (2) are isomorphous. In all chelates the Mo atom is in a distorted octahedral environment.
