platinum(II) fluoroaryl complex [PtI(κC-2-C6F4AsPh2)(1,5-COD)] (7), in which the arsenic atom is not coordinated to the metal atom. Attempts to prepare the bis(chelate) complex [Pt(κ2As,C-2-C6F4AsPh2)2] analogous to the known phosphorus compound failed. Removal of iodide ion from 7 with TlPF6 gave [Pt(κ2As,C-2-C6F4AsPh2)(1,5-COD)]PF6 (8), in which 2-C6F4AsPh2 is now coordinated as a bidentate ligand, giving
的反应[PTI 2与2- LIC(1,5-COD)] 6 ˚F 4 ASPH 2,得到平坦的铂(II)氟化芳基配合物[PTI(κ ç -2-C 6 ˚F 4 ASPH 2)(1, 5-COD)](7),其中,所述砷原子不配位到金属原子。尝试制备双(螯合物)络合物[PT(κ 2如,Ç -2-C 6 ˚F 4 ASPH 2)2 ]类似于失败已知磷化合物。碘化物离子的去除从7与TlPF 6,得到[PT(κ 2如,Ç -2-C 6 ˚F 4 ASPH 2)(1,5-COD)] PF 6(8),其中2-C 6 ˚F 4 ASPH 2现在被作为配位的二齿配位体,给一个四元螯合环。可替代地,质子分解(与三氟甲磺酸)的甲基络合物[PTME(κ ç -2-C 6 ˚F 4 ASPH 2)(1,5-COD)](15),这是从获得7和二甲基锌,给人的三氟甲磺酸酯盐16相同的螯合阳离子的。螯合如,在CRING 8
