| Description | Syntheses and structures of three new lanthanide coordination compounds with dithiocarbamate ligands are reported. The complexes [Ln(Me2dtc)3(phen)] (Ln = Pr (1), Nd (2) and Gd (3), Me2dtc = N,N-dimethyldithiocarbamate and phen = 1,10-phenanthroline) were synthetized by a simple metathesis between lanthanide(III) nitrate and sodium dimethyldithiocarbamate followed by addition of 1,10- phenanthroline without the exclusion of moisture. Single crystal X-ray analysis showed that all three complexes are isostructural, crystallizing in the triclinic space group P-1. The Ln-S and Ln-N bond lengths decrease in agreement with the decrease in ionic radii across the lanthanide series. Similar structures with Et2dtc ligands show no significant effect on the changes of Ln-S bond lengths and also on the S-Ln-S bite angles. The crystal packing of described complexes is formed via pi-pi stacking interactions and C-H…S non-covalent contacts. |
