Structural tuning of coordination polymers by 4-connecting metal node and secondary building process

摘要

Five transition metal coordination polymers,{[Cu(4-pmntd)2(NO3)2]·2CHCl3}n (1),{[Cu(4-pmntd)2(NO3)2]· 3C7H8}n (2),{[Cu(4-pmntd)2(CF3SO3)(H2O)]·CF3SO3·H2O·CH3OH}n (3),[Cd(4-pmntd)2]n·nSiF6·x(CH3OH)· y(CHCl3)(4), and [Zn(4-pmntd)2(CF3SO3)2]n·x(solvent)(5), have been obtained from a ditopic ligand, N,N'-bis(4-pyridylmethyl)naphthalene diimide (4-pmntd). Either sql-or dia-structures are generated from four connecting coordination nodes of the metal centers. While delicate interpenetration and structural tuning in these complexes is achieved by the different conformations and spatially extending geometries adopted by the ligand and"secondary building process"induced by pillar-like anions.
