K. Severin et al., METAL-COMPLEXES CONTAINING BIOLOGICALLY I MPORTANT LIGANDS .81. SYNTHESIS AND CRYSTAL-STRUCTURE OF RHODIUM(I) CHELATES WITH ALPHA-AMINO CARBOXYLATES, Chemische Berichte, 128(11), 1995, pp. 1127-1130
The alpha-amino carboxylate complexes (Ph(3)P)(OC)RhNH2-C(H)(R)CO2 (R
= Me, CH(2)Ph = 1, 2) were prepared from Rh(Cl)(CO)(PPh(3))(2) and H2N
C(H)(R)CO2- in the presence of AgBF4 and characterized by X-ray diffra
ction. In the crystal the complexes form chains by hydrogen bridges be
tween amino and carboxylate groups of adjacent molecules.
