 Title    Dioxomolybdän(VI)-Komplexe mit dreizähnigen diaciden Liganden Dioxomolybdenum(VI) Complexes with Tridentate Diacidic Ligands  
 Abstract    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'-dihydroxy-azobenzenato(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) (la): a = 23.381(6) Ä, b = 6.756(2) A, c = 28.380(8) A, ß = 124.47(2)°; Salicylaldehyde-2-hydroxyanilato(2-)-triphenylphosphaneoxide-dioxomolybdenum (VI) (lb): a = 9.4208(14) A, b = 30.550(5) A, c = 10.461(2) Ä, ß = 111.005(17)°; 2,2'-Dihydroxy-azobenzenato(2-o)-triphenylphosphaneoxide-dioxomolybdenum(VI) (2): a = 9.392(2) A, b = 31.012(13) A, c = 10.350(2) Ä, /3 = 110.968(17)°; Salicylaldehyde-salicylhydrazonato(2-0)-triphenylphosphaneoxide-dioxomolybdenum(VI) (3): a = 9.321(2) A, b = 12.048(2) A, c — 13.858(3) A, a = 101.90(2)°, ß = 94.94(2)°, 7 = 105.479(17)°.
