A convenient approach on transesterification to preparing the complexee of β-alkoycarbonylethyltin trichlorides with dibenzylsulfoxide (DBSO) andhexametkylphosphoramide (HMPA) was reported. The structures of complexes were characterized by elemental analysis, IR, 1HNMR and X-ray single crystal *** possible mechanism for the transesterification of complexes of β-onylethyltin trichloride with an alcohol was suggested

The crystal structure of tris-(dimethoxyphosphato) lanthanum(Ⅲ) coordination polymer, {La[PO2(OCH3)2]3}n, has been determined from single crystal X-ray diffraction data. The crystal is triclinic, space group P1 with a= 9. 625 (2) , b=10. 418(2) , c=11. 352(4) A, ai13.05(2) ,β=107. 33(2) ,γ=62. 22 (2)°and Z=2, (La[PO2(OCH3)2]3, V= 917. 4(4) A, Dc= 2. 466 gcm-3,λ(MoKα) =0. 71073 A, μ=26. 64 cm-1, F(000) =504, final R=0. 0625 for 4839 unique reflections with I>3σ(Io). The lanthanum ions are coordinated in a distortional octahedral arrangement to six oxygen atoms from six bridging ligands with a mean neighbour O-La-O angle of 90. 8° and a mean La-O distance of 2.437 *** polymer networks of metal ions are linked by phosphate bridges, and the adjacent network layers are held together only by Van der waals interaction.

Three-component IPNs were synthesized from polyurethane/poly (methyl acrylate aminoethyl methacrylate)/epoxy resin [PU/P(MADMA)/EP] by simultaneous synthesis interpenetrating polymer networks method(SINs) and sequential synthesis interpenetrating polymer networks method (STPNs). Comparing the effect of the two synthesis methods on the morphology and mechanical properties of three-component IPNs, it was found that the compatibility of three-component IPNs depends on the component ratios and interpenetrating formation , the different synthesis methods make the entanglement and interpenetrating between networks changed. The tensile strength of SIPNs is bigger than that of SINs, while the elongation at break of SINs is bigger than that of SIPNs. It is feasible to use stepwise staining method to observe the morphology change.

The synthesis of a new series of chiral Schiff base containing 2-hydroxybenzilideneaniline moieties as mesogenic core is presented. Differential scanning calorimetry and optical polarizing microscopy were used to study the phase transition temperature and *** results reveal that all of them are mesomorphic and most of them show chiral smectic mesomorphism.
