 Title    Präparative, spektroskopische und kristallographische Untersuchungen an Phosphinato-Komplexen des Rheniums mit verschiedenen einzähnigen Liganden Preparative, Spectroscopic and Crystallographic Investigations on Phosphinato Complexes of Rhenium with Various Unidentate Ligands  
 Abstract    The stable phosphinato complexes [^-R2P02Re(C0)3L]" (1, 2b-f) [L = THF (a), py (b), NH3 (c), P(C6H5)3 (d), AS(C6H5)3 (e), P(C6Hn)3 (f), 0(C2H5)2 (g)] are obtained by addition of the ligands L to the compounds 0-R2P02Re(C0)3]M (1, 2) [R = CH3 (1), C6H5 (2)] at 20-40 °C (1, 2c: —35 °C). 1, 2b, d, e are also formed when THF in 1, 2a is substituted by the ligands b, d, and e. The unstable ether adducts 1, 2g which result photochemically from Re2(CO)io and the acids R2P02H, are transformed to 1, 2 by elimination of ether. At 20 °C 1, 2 a react with liquid ammonia to give the ionic complexes [(0C)3Re(NH3)3][02PR2] (1, 2h). On the basis of their mass and vibrational spectra, and a crystallographic in-vestigation, the methyl [la-f] and phenyl compounds [2 a-f] are dimeric and oligomeric, respectively. The rhenium atoms are bridged via R2P02~ ligands (phosphinato-0,0'). la crystallizes monoclinic in the space group C2/m with Z = 2. Stabile, monomere Chelatkomplexe des Mangans und Rheniums mit zweizähnigen Carboxylat-oder Phosphinat-Liganden des Typs RCE2M(CO)3L bzw.
