complex containing a xantphos dioxide chelating ligand.

Abstract
The reaction of xantphos dioxide (O\O) with the polynuclear precursor [Ru(CO)2Cl2]n to give the mononuclear
complex [Ru(CO)2Cl2(O\O)](1) is reported together with single crystal X-ray structure analyses of
both the free ligand and the ruthenium complex. The synthesized compounds have also been characterized
by elemental analyses, IR and NMR (1H, 31P and 13C) spectroscopy. The ligand O\O crystallizes with
lattice water molecules in a triclinic system with space group P�1 whereas the complex 1 crystallizes in an
orthorhombic system with space group P212121. Each mononuclear unit of O\O and 1 is stabilized in
their solid state through non-covalent (C–H���O, C–H���Cl and C–H���p) interactions to develop an extended
three-dimensional network structure. The complex 1 exhibits an interesting intramolecular O���O interaction
between one of the P@O groups and backbone O leading to different electron donacity of two P@O
groups to the metal centre.
