چکیده

The synthesis and structural characterization of six dicyanamido-cadmium(II) complexes are reported: catena-[Cd(μ1,3-dca)(μ1,5-dca)(3-ampy)] (1), catena-[Cd3(μ1,3,5-dca)2(μ1,5-dca)4(pyNO)2(H2O)2] (2), catena-{Cd(H2O)2(μ1,5-dca)2](2,6-lut-NO)} (3), catena-[Cd(Me2en)(μ1,5-dca)2] (4), catena-[Cd(Me4en)(μ1,5-dca)2] (5), [Cd(1,8-damnp)2(dca)2] (6), where dca = dicyanamide anion, 3-ampy 3-aminopyridine, pyNO pyridine-N-oxide, 2,6-lut-NO 2,6-lutidine-N-oxide, Me2en N,N-dimethyl-ethylenediamine, Me4en N,N,N′,N′-tetramethyl-ethylenediamine, 1,8-damnp 1,8-diaminonaphthaline. coordination polymers have different dimensionalities: 1 5 form 3D networks structures; 3 4 polymeric 1D chains 1DD double chains, respectively. Ribbons three fused observed in 2. In 6, the mononuclear complex units a hydrogen-bonded supramolecular network. polymer compounds, linkers display bonding modes: most common μ1,5-dca least popular μ1,3- μ1,3,5-dca bonding. luminescence emission thermal properties were investigated.

Chemistry of porous coordination polymers

Remarkable advances in the recent development of porous compounds based upon coordination polymers have paved the way toward functional chemistry having potential applications such as gas storage, separation, and catalysis. From the synthetic point of view, the advantage is a designable framework, which can readily be constructed from building blocks, the so-called bottom-up assembly. Compared ...
