Synthesis and characterization of metal dithiocarbamate derivatives of (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline

چکیده مقاله

Five metal dithiocarbamate complexes [M(PTHIQDTC)₂] [where PTHIQDTC is (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline dithiocarbamate anion and M is Ni(II) (1), Sn(II) (2), Hg(II) (3), Pb(II) (4) and Zn(II) (5)] were synthesized from the reaction of MX₂ (X is Cl^– for 1–3 and OAc^– for 4–5) with ligand of triethylammonium (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline dithiocarbamate [Et₃NH][PTHIQDTC] in methanolic solution at room temperature. The five complexes were characterized by IR, ¹H and¹³C NMR, mass spectrometry, elemental analysis and TGA analysis. Recrystallization of [Zn(PTHIQDTC)₂] (5) in dimethylsulfoxide (DMSO) converts 5 to [Zn(PTHIQDTC)₂(DMSO)] (6). The structure of complex 6 has been determined by X-ray crystallography. The X-ray structural analysis of 6 indicated that the zinc(II) is five-coordinated in a distorted trigonal-bipyramidal by four S atoms from two (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline dithiocarbamate anion ligands (PTHIQDTC) and one O atom from DMSO. © The Author(s) 2024.
