摘要：

Dioxomolybdenum(VI) complexes have been synthesized by ligand exchange reactions of Mo(CO)6, Mo(NO)2(acac)2 and MoO2(acac)2 with tridentate diacidic ligands. X-ray structure analyses were performed on single crystals. The complexes salicylaldehyde-2-hydroxyanilato(2-)-triphenylphosphaneoxide-dioxomolybdenum(VI) (1b) and 2,2′-dihydroxyazobenzenato(2-)-triphenylphosphaneoxide-dioxomolybdenum(VI) (2) are isomorphous. In all chelates the Mo atom is in a distorted octahedral environment. Structural data: Salicylaldehyde-2-hydroxyanilato(2-)-tetrahydrofurane-dioxomolybdenum (VI) (1a): a = 23.381(6) Å, b = 6.756(2) Å, c = 28.380(8) Å, β = 124.47(2); Salicylaldehyde-2-hydroxyanilato(2-)-triphenylphosphaneoxide-dioxomolybdenum (VI) (1b): a = 9.4208(14) Å, b = 30.550(5) Å, c = 10.461(2) Å, β = 111.005(17); 2,2′-Dihydroxyazobenzenato(2-)-triphenylphosphaneoxide-dioxomolybdenum(VI) (2): a = 9.392(2) Å, b = 31.012(13) Å, c = 10.350(2) Å, β =110.968(17); Salicylaldehyde-salicylhydrazonato(2-)-triphenylphosphaneoxide- dioxomolybdenum(VI) (3): a = 9.321(2) Å, b = 12.048(2) Å, c = 13.858(3) Å, α = 101.90(2), β = 94.94(2), γ = 105.479(17).
