The crystal and molecular structures of 2,4-Br2C6H3OCH(CH3) CO2Sn(C6H11),CH3(Ⅰ)and 2-OCH3-4-CH3CH=CHC6H3OCH2CO2Sn(C6H11)2CH3(H2O)(Ⅱ) are reported here. The crystallographic data are as follows:Two crystals are monoclinic,space group of(Ⅰ) is P21/c,a=13.067(3),b=10.594(3),c=18.157(4),β=106.99(2)°,V=24037A3,Z=4,Dc=1. 672 g/cm3,Mr=622.99,μ=43.731 cm(-1),F(000)=1232.the final R=0.046,Rω=0. 046for 2856 reflections withⅠ>3σ(Ⅰ);Space group of (Ⅱ) is P21/n,a=10.409(1),b=12.570(2),c=20.664(2),β=83.51(1)°,V=2686.4A,Z=4,Dc=1.281 g/cm3,Mr=539.28,μ=9.761 cm-1,F(000)=1120,the final R=0.049,Rω=0.047 for 3081 reflections with Ⅰ>3σ(Ⅰ) .The tin atoms in both title compounds have five ligands of 3 carbon and 2 oxygen atoms,forming a distorted triangle-dicone,the cyclohexyls in above compounds are the conformation of chair.In crystal(Ⅱ),the H2O coordinating with Sn forms two strong hydrogen bonds with the carbonyl and methyloxyl oxygen atoms of other molecule.The dihedral angles between axatyl and benzle planes are 77.37°and 153.48°respectively.
