Coordination Polymers in Dicyanamido-Cadmium(II) with Diverse Network Dimensionalities
The synthesis and structural characterization of six dicyanamido-cadmium(II) complexes are reported: catena-[Cd(mu(1,3)-dca)(mu(1,5)-dca)(3-ampy)] (1), catena-[Cd-3(mu(1,3,5)-dca)(2)(mu(1,5)-dca)(4)(pyNO)(2)(H2O)(2)] (2), catena-{Cd(H2O)(2)(mu(1,5)-dca)(2)](2,6-lut-NO)} (3), catena-[Cd(Me(2)en)(mu(1,5)-dca)(2)] (4), catena-[Cd(Me(4)en)(mu(1,5)-dca)(2)] (5), and [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, Me(2)en = N,N-dimethyl-ethylenediamine, Me(4)en = N,N,N ‘,N ‘-tetramethyl-ethylenediamine, and 1,8-damnp = 1,8-diaminonaphthaline. The coordination polymers have different dimensionalities: 1 and 5 form 3D networks structures; 3 and 4 form polymeric 1D chains and 1DD double chains, respectively. Ribbons of three fused polymeric chains are observed in 2. In 6, the mononuclear complex units form a hydrogen-bonded supramolecular 3D network. In the coordination polymer compounds, the dca linkers display three bonding modes: the most common mu(1,5)-dca and the least popular mu(1,3)- and mu(1,3,5)-dca bonding. The luminescence emission and thermal properties of the complexes were investigated.
