Mcl. Gallegopreciado et al., THE CRYSTAL AND MOLECULAR-STRUCTURE OF BIS(INDAZOL-1-YL)PYRIDIN-2'-YLMETHANE (BIPM) AND [RH(BIPM)(NBD)]PF6, Journal of organometallic chemistry, 450(1-2), 1993, pp. 237-244
The syntheses of a new tripodal ligand bis(indazol-1-yl)pyridin-2'-ylm
ethane (BIPM) and of a cationic complex [Rh(BIPM)(NBD)]PF6, (NBD = 2,5
-norbornadiene) are reported. Both compounds were characterized by inf
rared, H-1, and C-13 NMR spectroscopy and by single crystal X-ray anal
ysis. BIPM crystallizes in the monoclinic system in space group P2(1)/
n with an alphabetaalpha helical conformation. The [Rh(BIPM)(NBD)]PF6
complex crystallizes in the monoclinic space group C/2c, the rhodium a
tom being pentacoordinate with a distorted trigonal bipyramidal geomet
ry.
