Derivatives of divalent germanium, tin, and lead. Part VI. Crystal and molecular structure of bis(1-phenylbutane-1,3-dionato)tin(II)

Abstract

The crystal structure of the title compound has been determined by Patterson and Fourier methods from X-ray diffractometer data. Crystals are monoclinic, space group C2/c, with a= 18.821 (2), b= 10.102(3), c= 9.733(3)Å, β= 101-57(2)°, Z= 4. The tin atoms are chelated by two crystallographically equivalent benzoylacetonatoligands resulting in distorted pseudotrigonal bipyramidal co-ordination with the lone pair of electrons occupying an equatorial site: r(Sn–O)(ax) 2.290(6), r(Sn–O)(eq) 2.135(1)Å, O(ax)–Sn–O(ax) 150.4(2), O(eq)–Sn–O(eq) 94.7(1)°.
