The title compound, (4R,5R)-1,3-dioxolance-4,5-bis(2-pyridineacrboxylic acid), has been synthesized and characterized by single-crystal X-ray diffraction, IR, NMR, and MS analyses. Crystal structure of the title compound was grown from ETOH by slow diffusion at room temperature. The title compound crystallizes in monoclinic, space group C2 with a = 17.805(3), b = 11.459(3), c = 11.1656(17) , β = 113.066(4)°, V = 2095.9(6) 3, Z = 4, F(000) = 880, Dc = 1.332 Mg/m-3, C23H20N2O6, Mr = 420.41 and μ = 0.10 mm-1 展开更多

Two novel drum organooxotin clusters [PhCH 2Sn(O) (O 2CC 5H 4N)] 6 (1) and [PhCH 2Sn(O)(O 2CC 4H 3O)] 6 (2) were synthesized by the reaction of [(PhCH 2) 3Sn] 2O with 2 pyridinecarboxylic acid and 2... Two novel drum organooxotin clusters [PhCH 2Sn(O) (O 2CC 5H 4N)] 6 (1) and [PhCH 2Sn(O)(O 2CC 4H 3O)] 6 (2) were synthesized by the reaction of [(PhCH 2) 3Sn] 2O with 2 pyridinecarboxylic acid and 2 furancarboxylic acid in 1∶2 molar ratio. Their structures were determined by X ray single crystal diffraction analysis. The crystal 1 belongs to monoclinic with space group P 2(1)/ c , a =1 2194(6) nm, b =1 2378(2) nm, c =2 6084(4) nm, β =94 148(3)°, Z =2, V =3 9270(11) nm 3, D c=1 765 kg/m 3, μ =1 951 mm -1 , F (000)=2040, R =0 0516, wR =0 0989 The crystal 2 belongs to orthorhombic with space group Pccn , a =2 0300(6) nm, b =2 2670(6) nm, c =1 6088(5) nm, β =90°, Z =4, V =7 404(4) nm 3, D c=1 813 g/cm 3, μ =2 070 mm -1 , F (000)=3936, R =0 0459, wR =0 0884. Their structures show a distorted octahedral configuration with six coordination for the central tin atom. 展开更多
