摘要：

A dialkyl tin complex of composition Bu2SnL2 (I) (L is a monofunctional bidentate ligand) has been made by reaction of ClBu2SnOSnBu2Cl with the substituted pyrazolone, PhCOC:C(OH)N(Ph)N:CCH3, in dry benzene. Crystals of I (M= 787.5) are monoclinic, space group P21/C, a= 9.714(6), b=19.621(6), c=22.68(1) Å, β=114.00(4)°, V=3949.2 Å3, Z=4, Dcalc=1.3240 cm-3, λ(Mo Kα)=0.71069 Å, μ=6.960 cm-1, T=295 K, F(000)=1624, R=0.0628 for 2187 unique reflections. The molecule has a distorted octahedral geometry with Bu groups trans to each other. Four oxygen atoms of the pyrazolone moieties and the central Sn atom lie in the same plane. © 1990.
