analysis, IR, TG, PL, powder and single-crystal X-ray diffraction. Owing to the terminal coordination of PPh3 molecules, complexes 1 and 2 only present [Cu2I2] cluster based dinuclear and chain structures. The in situ oxidized Cu(II) cation in complex 3 is triply coordinated by both the pyridyl N and aliphatic N atoms, thus forming mononuclear motif. In contrast, r-L1 and r-L2 ligands in complexes 4 and
摘要碘化亚铜[Cu(I)]和五个柔性双(吡啶基)配体的自组装生成了五个络合物[CuI(L1)(PPh3)] 2·2H2O(1),[Cu2I2(L2)(PPh3)2 ] n·2nCH2Cl2(2),[CuI2(L3)](3),[Cu3I3(r-L1)] n(4)和[Cu3I3(r-L2)] n·nH2O(5)(PPh3 =三苯基膦, L1 = N,N'-双(吡啶-4-基亚甲基)丙烷-1,3-二胺,L2 = N,N'-双(吡啶-3-基亚甲基)丙烷-1,3-二胺,L3 = N, N'-双(吡啶-2-基亚甲基)丙烷-1,3-二胺,r-L1 = N,N'-双(吡啶-4-基甲基)丙烷-1,3-二胺,r-L2 = N, N'-双(吡啶-3-基甲基)丙烷-1,3-二胺)已通过元素分析,IR,TG,PL,粉末和单晶X射线衍射表征。由于PPh3分子的末端配位,复合物1和2仅存在基于[Cu2I2]团簇的双核和链
