Piperazine-Bridged Homodinuclear Transition Metal Complexes

“…In the compound [{Cu(etdtc)} 2 ppzdtc], a triplet was observed at 0.79 ppm for the methyl protons of diethyldithiocarbmato-groups, whereas the methylene protons were found to resonate at 3.73 ppm as multiplet. 28 Another singlet at 3.45 ppm was also observed corresponding to eight protons of the piperazine moiety, thus confirming the proposed structure of the compound (Scheme 2).…”

Synthesis, spectral characterization, crystal structures of lanthanide(III) pyrrolidine dithiocarbamate complexes and their catalytic activity

“…The average bond length (Å) of C-S bond in these complexes is 1.72, which is significantly shorter than the C-S single bond length (1.81) and higher than the C=S distance (1.69). The observed intermediate value between the single bond (C-S) and the double bond (C=S) distances showed a partial double bond nature of the S¤C¤S bonds [15].…”

Synthesis, crystal structures, luminescence properties and catalytic application of lanthanide(III) piperidine dithiocarbamate complexes

“…In these three complexes, the average length (Å) of C-S bond is 1.7138(4) which is significantly shorter than the CÀS single bond length (1.81) and higher than the C@S distance (1.69). The observed intermediate value between the CÀS and C@S bond distances indicated that a partial double bond nature arises due to the chelated sulfur atoms [18]. The powder XDR patterns of the complexes 6 and 9 (as representative cases) for which we are not able to prepare single crystals are also recorded to have an insight into the structure of the complexes.…”
