Synthesis and crystal and molecular structure of mixed-ligand compounds Eu(S2CN(C2H5)2)3(2,2′-Bipy) and Eu(S2CN(C2H5)2)3(1,10-Phen)

Synthetic procedures were developed and X-ray diffraction analysis was performed for two mixed-ligand compounds of europium(III) with diethyldithiocarbamate ions and 2,2′-bipyridyl (2,2′-Bipy) or 1,10-phenanthroline (Phen): Eu(S₂CN(C₂H₅)₂)₃(2,2′-Bipy) (I) and Eu(S₂CN(C₂H₅)₂)₃Phen (II). The structures of the complexes consist of discrete monomer molecules; the coordination polyhedron of Eu (EuN₂S₆ is a node) is a distorted dodecahedron.
