    • Abstract

       

      The reaction of [(η6-p-cymene)Ru(μCl)2Cl2] with functionalized phosphine viz, diphenyl-2-pyridylphosphine yielded complexes of the type: (a) P-bonded complex [(η6-p-cymene)RuCl2(PPh2Py)] (1), (b) P-, N-chelated complex [(η6-p-cymene)RuCl-(PPh2Py)]BF4 (2) and [RuCl2(PPh2Py)2] (3) resulting from the displacement of thep-cymene ligand. These complexes were characterized by1H NMR,31P NMR and analytical data. The structures of complexes1 and2 have been confirmed by single crystal X-ray diffraction study. Complex1 crystallised in triclinic space groupP 1 witha = 10.9403 (3) Å,b= 13.3108 (3) Å,c= 10-5394 (10) Å, α=88.943 (2)°, β = 117.193 (2)°, γ= 113.1680 (10)°, Z=2 andV= 1230.39 (5) Å3. The complex2 crystallises in monoclinic space group P21 witha = 9.1738 (4) Å,b = 14.0650 (6) s, c = 10.7453 (5) Å, β= 106.809 (1)°, Z = 2 andV= 1327.22 (10) Å3
