The 1:1-adduct of chlorotriphenyltin with 2',6'-dimethoxyflavone : a potential fungicide

The 1:1 adduct of chlorotriphenyltin with 2',6'-dimethoxyflavone, (C sub(35)H sub(29)O sub(4)ClSn) Mr = 667.78, crystallizes in the triclinic space group P1avg 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) degree , V = 1503.8(4) Angstrom super(3), Z = 2, Mo-K alpha , mu = 9, 8 cm super(-1), Dc = 1.475 g cm super(-3), F(000) = 676, T = 293K. The structure was solved by direct-methods and has been refined to a final R value (I > 3 sigma (I)) of 0.0301. The flavone coordinates to the tin atom through the carbonyl oxygen atom. The metal center exhibits a trigonal bipyramidal configuration with the three phenyl groups in equatorial positions.
