The crystal structure of (1) has been determined by X-ray crystallographic methods.The compound crystallises in the monoclinic space group C2/c with a=14.002(6), b=13.059(7), c=19.158(8) Angstroem, β=96.00(3)o, and Z=4.The molecule is disordered over two orientations in the crystal and possesses a crystallographically imposed C2 axis passing through the W atom.The disordered atoms are Cl(2) and O(2).Molecular dimensions are W-Cl(1), 2.369(4); W-O(1), 2.088(11); W-Cl(2), 2.242(10); and W-O(2), 2.053(22) Angstroem.Single-crystal e.s.r. spectra of (1) diluted in the niobium analogue gave g1=1.739 +/- 0.002, g2=1.763 +/- 0.002, and g3=1.770 +/- 0.002, whilst a similar study on gave g=1.806 +/- 0.001 and g=1.765 +/- 0.001.The e.s.r. data for , , and 2> are discussed in terms of an angular-overlap model for their electronic structures.
