THE 1 1-ADDUCT OF CHLOROTRIPHENYLTIN WITH 2',6'-DIMETHOXYFLAVONE - A POTENTIAL FUNGICIDE/

The 1:1 adduct of chlorotriphenyltin with 2',6'-dimethoxyflavone, (C35 H29O4ClSn) Mr=667.78, crystallizes in the triclinic space group <P(1)o ver bar> with the following data: a=9.094(2), b=12.369(3), c=14.674(3) Angstrom, alpha=74.78(2), beta=77.00(2), gamma=73.06(3)degrees, V=150 3.8(4) Angstrom(3), Z=2, Mo-K alpha, mu=9, 8 cm(-1), Dc=1.475 g cm(-3) , F(000)=676, T=293K. The structure was solved by direct-methods and h as been refined to a final R value (I >3 sigma(I)) of 0.0301. The flav one coordinates to the tin atom through the carbonyl oxygen atom. The metal center exhibits a trigonal bipyramidal configuration with the th ree phenyl groups in equatorial positions.
