双性癌是混合性腺神经内分泌癌(mixed adenoneuroendocrine carcinoma,MANEC)的特殊类型,定义为肿瘤细胞同时具有腺上皮和神经内分泌分化。MANEC相对罕见,双性癌则更为罕见,目前仅有几例报告,主要发生在胃[1-4]、胰腺[5]、肝[6]和壶腹... 双性癌是混合性腺神经内分泌癌(mixed adenoneuroendocrine carcinoma,MANEC)的特殊类型,定义为肿瘤细胞同时具有腺上皮和神经内分泌分化。MANEC相对罕见,双性癌则更为罕见,目前仅有几例报告,主要发生在胃[1-4]、胰腺[5]、肝[6]和壶腹部[7]。 展开更多

Bis-[oxo-bis(p-ferrocenylbenzoxy di-n-propyltin)] I and bis-[oxo-bis(-ferrocenoyl- propionyloxy di-n-propyltin)] II were synthesized and their crystal structures have been determined by X-ray diffraction analysis. The compound I2C6H6 ([(FcC6H4COOSnPr2)2O]22C6H6 or C92H108Fe4O10Sn42C6H6, Mr = 2384.16) is of triclinic, space group P?with a = 12.826(4), b = 13.099(5), c = 17.539(5) ? = 78.229(5), ?= 71.852(5), = 62.746(5)? V = 2483(1) ?, Z = 1, Dc = 1.490 g/cm3, = 0.71073 ? (MoK? =1.611 mm-1 and F(000) = 1128. The structure was refined to R = 0.0491 and wR = 0.1053 for 4690 unique reflections with I > 2(I). The compound IIC6H6 ([(FcCOCH2CH2COOSnPr2)2O]2C6H6 or C80H108Fe4O14Sn4C6H6, Mr = 2115.93) is of triclinic, space group P?with a = 11.260(4), b = 14.126(5), c = 15.961(6) ? = 91.400(6), = 110.654(6), = 104.931(6), V = 2277(1) 3, Z = 1, Dc = 1.510 g/cm3, = 0.71073 ? (MoK? = 1.750 mm-1 and F(000) = 1046. The structure was refined to R = 0.0466 and wR = 0.1138 for 5061 unique reflections with I > 2(I). The two compounds have the similar structures: both are dimers containing centrosymmetric Sn2O2 cores. But there are some differences in the ligating modes between the carboxylate groups and the Sn atoms. 展开更多
