Preferred Abstract (Original):

Three diamine-bis(diphenylphosphinobutane)ruthenium(II) complexes, isolated from the reaction of [Cl₂Ru(dppb)] with diamines viz., 2,2-dimethyl-1,3-diamnopropane, 1,2-diaminocyclohexane and 1,8-diaminonaphthalene are reported. The synthesized complexes have been characterized on the basis of various physico-chemical studies viz., EDX, IR, FAB-MS, UV/Vis, NMR, TG-DTG and EXAFS studies. ³¹P NMR investigations confirm that the complex 3 is in cis form while the complexes 1–2 appear in trans form. The structure of complex 3 has been additionally determined by single crystal X-ray diffraction showing solvated dichloromethane. Furthermore, complex 3 crystallizes as monoclinic unit cell with P2(1)/n space group.

Preferred Abstract (Original):

Three diamine-bis(diphenylphosphinobutane)ruthenium(II) complexes, isolated from the
reaction of [Cl2Ru(dppb)] with diamines, have been synthesized and characterized on the basis of
various physico-chemical studies viz., elemental analyses, IR, UV/Vis, FAB-MS, TG-DTA,
EXAFS, EDX and 1H-, 13C- and 31P{1H}NMR spectroscopy. 31P{1H}NMR investigations
confirm that the complex 3 is in cis form while the complexes 1-2 appear in trans form. The
structure of complex 3, cis-[Cl2Ru(dppb)(N-N)] isomer, determined by single crystal X-ray
measurement shows with one solvated dichloromethane and crystallize as monoclinic unit cell
with P2(1)/n space group.
