Abstract
The structure of solvated cadmium(II) ion and the tetrathiocyanatocadmate(II) complex in N,N-dimethylformamide (DMF) has been determined by means of X-ray diffraction at 25 °C. The radial distribution curve for a cadmium(II) perchlorate DMF solution is well explained in terms of the presence of the octahedral [Cd(dmf)6]2+ complex with the Cd–O bond length of 229.6(4) pm, which is practically the same as that within [Cd(dmso)6]2+ in DMSO and [Cd(H2O)6]2+ in H2O. It is also found that the tetrathiocyanatocadmate(II) complex has a tetrahedral structure, [Cd(NCS)3(SCN)]2−, with three Cd–N and one Cd–S bonds, the distances being 223(2) and 257(2) pm, respectively. The coordination structure of the complex in DMF is different from that found in aqueous solution, [Cd(NCS)2(SCN)2]2−.This publication has 10 references indexed in Scilit:
