The crystal and molecular structure of bis(indazol-1-yl)pyridin-2′-ylmethane (BIPM) and [Rh(BIPM)(NBD)]PF6
摘要:
The syntheses of a new tripodal ligand bis(indazol-1-yl)pyridin-2'-ylmethane (BIPM) and of a cationic complex [Rh(BIPM)(NBD)]PF6, (NBD = 2,5-norbornadiene) are reported. Both compounds were characterized by infrared, H-1, and C-13 NMR spectroscopy and by single crystal X-ray analysis. 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 atom being pentacoordinate with a distorted trigonal bipyramidal geometry.
