TLDR
The ternary complexes [Pd(RaaiX)(SS)ClO4] as discussed by the authors, where RaaiX is a N(1)-alkyl-2-(arylazo)imidazole (p-RC6H4N =NC3H2NN(1) X; X = Me, or Et, and R = H, Me or Cl) and SS = N,N-diethyldithiocarbamate or morpholinedithiamato (II) in solution.Abstract:
The ternary complexes [Pd(RaaiX)(SS)ClO4) where RaaiX is a N(1)-alkyl-2-(arylazo)imidazole (p-RC6H4N =NC3H2NN(1) X; X = Me, or Et, and R = H, Me or Cl) and SS = N,N-diethyldithiocarbamate or morpholinedithiocarbamate have been prepared and characterized by elemental analysis, i.r., u.v.-vis. and 1H-n.m.r. data. Electrochemical studies show azo reduction. The complexes are thermally unstable and decompose to bis(dithiocarbamato)palladium(II) in solution.read more

Synthesis, spectral and electrochemical studies of 2-(arylazo)heterocycle complexes of zinc(II). Single-crystal X-ray structure of [Zn(papm)Cl2·CH3OH] (papm=2-(phenylazo)pyrimidine)
TL;DR: In this paper, single-crystal X-ray structure of dichloro-{2-(phenylazo)pyrimidine}zinc(II)·methanol suggests that the complex is a distorted trigonal bipyramidal symmetric around Zn(II), and Cl(1), Cl(2), N(4) (N (azo)) make the trigonal plane.

Kinetics and Mechanism of the Reactions of Picolinic Acid with Dichloro-{1-alkyl-2-(arylazo)imidazole}palladium(II) Complexes
TL;DR: In this article, the reaction between Pd(N,N′)Cl2 and picolinic acid (picH) was studied spectrophotometrically at λ = 463 nm in MeCN at 298 K. The product is [Pd(pic)2] which has been verified by the synthesis of the pure compound from Na2[PdCl4] and picH.

Structural and electronic effects of alkyl substituents on the main group dithiocarbamato complexes: crystal and molecular structures of tris(N,N′-iminodiethanoldithiocarbamato)metal(III) complexes (M As, Sb and Bi) and cyclic voltammetric studies on substituted dithiocarbamates
TL;DR: In this paper, the crystal structures of dithiocarbamates of AsIII, SbIII and BiIII were determined by single crystal X-ray analysis, and the results showed that the reduction process occurs around −1.0 V for As and Sb complexes and around −0.5 V for Bi complexes which are completely irreversible.
