Ee. Nifantyev et al., SYNTHESIS AND STRUCTURAL FEATURES OF TETRANUCLEAR RHODIUM COMPLEXES OF AMIDOPHOSPHITO-AVITAND AND PHOSPHITOCAVITAND, Russian chemical bulletin, 47(9), 1998, pp. 1805-1811
Interactions of acetylacetonatodicarbonylrhodium(I) with amidophosphit
o- and phosphitocavitands were studied. First representatives of tetra
nuclear cavity complexes of rhodium(I) were obtained. It was establish
ed by NMR spectroscopy and X-ray diffraction studies that the chemical
ly identical phosphorhodium centers in these complexes differ in the s
patial arrangement, and the system as a whole becomes unsymmetrical.
