摘　　要：本文报道具有梯状架构Sn_(4)O_(4)的二丁基锡乙酸酯(1)和一维链状配位聚合物三丁基锡乙酸酯锡氧簇合物(2),化合物1,C_(36)H_(78)O_(8)Sn_(4),M=1113.74,单斜晶系C2/c空间群,a=2.5064(2),b=1.14776(8),c=3.5155(2)nm,β=91.173(2)°,V=10.1113(13)nm^(3),Z=8,D=1.463g/cm^(3),最终R_(1)=0.0523和wR_(2)=0.1453,由μ^(2)-O和μ^(3)-O分别桥联2个和3个二丁基锡形成平面梯状结构,平面上、下的丁基由于空间影响而不能自由移动,梯状结构相对稳定。化合物2,C_(56)H_(120)O_(8)Sn_(4),M=1396.27,单斜晶系P21/c空间群,a=1.0399(3),b=2.1012(5),c=1.6607(4),β=92.600(4),V=3.6248(16)nm^(3),Z=2,D=1.279g/cm^(3),R_(1)=0.0468,wR_(2)=0.1367。通过羧基与三丁基锡双齿桥联,形成一维链状配位聚合物。中心锡原子与5个配位原子组成五配位畸形三角双锥。In this paper,the ladder dibutyltin acetate(1)with Sn_(4)O_(4) structure and one-dimensional chain coordination polymer tributyltin acetate tin-oxo cluster(2)are reported.The compound 1,C_(36)H_(78)O_(8)Sn_(4),M=1113.74,monoclinic C2/c space group,a=2.5064(2),b=1.14776(8),c=3.5155(2)nm,β=91.173(2)°,V=10.1113(13)nm3,Z=8,D=1.463 g/cm3,final R_(1)=0.0523 and wR_(2)=0.1453,byμ^(2)-O andμ^(3)-O bridges 2 and 3 dibutyltin respectively to form a planar ladder structure.The butyl above and below the plane cannot move freely due to the influence of space,and the ladder structure is relatively stable.The compound 2,C_(56)H_(120)O_(8)Sn_(4),M=1396.27,monoclinic P2_(1)/c space group,a=1.0399(3),b=2.1012(5),c=1.6607(4),β=92.600(4),V=3.6248(16)nm^(3),Z=2,D=1.279 g/cm3,R_(1)=0.0468,wR_(2)=0.1367.A one-dimensional chain coordination polymer is formed by bidentate bridging of carboxyl group and tin atom.The central tin and the coordination atom form a five-coordinated distorted triangular bipyramids configuration.
