三氟甲基磺酸银与1,4-二咪唑基二甲苯(bix)在双膦配体参与下的自组装:零维金属大环配合物或二维配位的聚合物

摘要

Assembly of silver triflate with 1,40-bis (imidazol-1-yl)exlene in the presence of a diphosphine Ph2P (CH2)n PPh2 (n=1 or 2) provided complexes [Ag4 (bix)2 (dppm)4 (CF3SO3)2]·2DMF·2H2O and [Ag (bix) (dppe)]n(2) (CF3SO3)n·nDMF·nCH3OH,where the cation 1 is a discrete 34-membered metallomacrocycle and 2 a polymeric 2D (4,4) grid network.The backbone (CH2)n of the diphsophine obviously plays the major role in the varied architectures.%AgCF3SO3与1,4-二咪唑基-二甲苯(bix)在双膦配体dppm或dppe参与下通过自组装得到结构迥然不同的两个配合物:零维金属大环配合物[Ag4(bix)2(dppm)4(CF3SO3)2](1)·2CF3SO3·2DMF·2H2O及具有二维(4,4)格子的聚合物[Ag(bix)(dppe)]n(2)·nCF3SO3·nDMF·nCH3OH,表明双膦配体的链上亚甲基的数目对配合物的结构有重要影响.
