Synthesis and Crystal Structure of a Three-dimensional Coordination Polymer {[Cd(cda)_2]·2CH_3OH}_n Generated from Cadmium(II) and Carbamyldicyanomethanide Anion Bridging Ligand |

| Abstract: | The three-dimensional coordination polymer {Cd(cda)2]2CH3OH}n has been syn- thesized by Na(cda) (cda = carbamyldicyanomethanide anion) and hydrated cadmium perchlorate in methanol solution. The crystal belongs to monoclinic, space group C2/c with a = 15.686(3), b = 8.1650(18), c = 13.119(3) ? b = 119.334(2), V = 1464.8(6) 3, Z = 4, C10H12CdN6O4, Mr = 392.66, Dc = 1.780 g/cm3, F(000) = 776 and m = 1.516 mm-1. The structure was refined to R = 0.0248 and wR = 0.0628 for 1176 observed reflections (I > 2s(I)). The Cd(II) ion is coordinated by two amide- oxygen and four nitrile-nitrogen atoms from six different cda bridging ligands, forming a three- dimensional structure. |
