 Title    Ligandenaustauschreaktionen von NiCl2(PPh3)2 mit 0(S)~N~S-Liganden Ligand Exchange Reactions of NiCl2(PPh3)2 with 0 (S )^ N ^ S Ligands  
 Abstract    Ligand exchange reactions of NiCl2(PPh3)2 with O (S)'"'N ^ S ligands were studied. Oxi­ dation products of O^N^S ligands have been characterized and their structures deter­ mined: 3-methyl-4H-benzo[b] [ 1,4]thiazin-2-yl-phenylmethanone / 2-methyl-benzo[d] [ 1,3]thi-azole (mixed crystal); [2-iminoisopropyl-thiophenolato(2-)](triphenyl-phosphane)-nickel(II); 1 -phenyl-3-methyl-4-(benzoyl-thiobenzoylhydrazono)-pyrazol-5-thione; [ 1 -phenyl-3-methyl-4-(benzoyl-thiobenzoylhydrazono)-pyrazol-5-thionato](triphenyl-phosphane)-nickel(II).

 Title    Synthesis and Ligand Exchange Reaction of Some Organotin(IV) Bis(N-arylsulphonyl-N-arylhydroxylaminates)  
 Abstract    Several diorganotin(IV)-bis(N-arylsulphonyl-N-arylhydroxylaminates) o f the general for­ mula R2S n [0 N (R ')S 0 2R2]2 have been synthesized and characterized by elemental analyses and by IR and 'H N M R spectra. A representative ligand exchange reaction with N-benzoyl-N-phenylhydroxylamine has been carried out.

 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)°.
