Abstract
FPPM–, BPPM– and PPPM–Rh+ (COD) complexes have the planar four cordinated structures, whereas PPM–Rh+(COD) complex has the trigonal bipyramidal five cordinated structure. Furthermore, the ratios between the rotational isomers of the complexes resulted from their N-substituent were clarified.This publication has 5 references indexed in Scilit:
