摘要: Abstract The crystal and molecular structures of the acaricides chlorotrineophylstannane ( 1a ), chlorotris[(dimethylphenylsilyl)methyl]stannane 1b trineophyl(1, 2, 4-triazol-1-yl)stannane hemihydrate 2a · 0.5H 2 O), have been determined by single-crystal X-ray diffraction studies. structure 5-dimethyl-2, 5-diphenylhexane 4 ) was also investigated for comparison. Binding three very bulky neophyl ligands around tin causes serious distortion tetrahedral geometry [ : C-Sn-C 117.2°, C-Sn-Cl 99.7°; O: 116.9° (mean), C-Sn-N 100.2° (mean)]. Replacement central carbon atoms in substituents silicon leads to a decrease steric strain hence much smaller 113.3° 105.3°
