Self-Assembly of Repeated Rhomboidal Coordination Polymers from 4,4‘-Dipyridyl Disulfide and ZnX2 Salts (X = SCN, NO3, ClO4)

摘要: 4,4‘-Dipyridyl disulfide, 4pds, reacted with ZnX2 to afford M:L 1:2 one-dimensional coordination polymers [Zn(SCN)2(4pds)2·(DMF)2]n [1·(DMF)2], [Zn(NO3)2(4pds)2]n (2), [Zn(NO3)2(4pds)2(H2O)2·(CH3OH)·(H2O)]n [2(H2O)2·(CH3OH)·(H2O)], [Zn(NO3)2(4pds)2(H2O)·(H2O)4]n [2(H2O)·(H2O)4], [Zn(ClO4)2(4pds)2(DMSO)2]n [3(DMSO)2], and [Zn(ClO4)2(4pds)2(H2O)2·(4pds)4]n [3(H2O)2·(4pds)4]. These compounds have repeated rhomboidal structures show a variety of guest inclusion properties without modification the backbone. The clathration chirality products are dependent on recrystallization solvents.
