TL;DR: The intermediate derivatives of the thermal decomposition of M(py)4(SCN)2 have distorted octahedral polynuclear structures as mentioned in this paper, and these derivatives have been obtained using visible reflection spectra and magnetic susceptibility measurements.

TL;DR: In this paper, the stability constants of the mixed complexes formed between iodide ions and the parent complexes cobalt(III)-cyclohexane-1,2-dione-dioxime and cobalt (III)-α-furyl-Dioxime in nonaqueous solutions were determined by spectrophotometric equilibrium measurements to study the effect of the solvent on the complex equilibria.

TL;DR: In this article, the stochastic properties of the thermal decomposition of Ni(pyNO)Cl2H2O (I, III, IV, VIII) and Ni(4-MepyNO)2Cl2(V, VI, VII) were studied.
Abstract: The stoichiometry of thermal decomposition was studied for the following compounds: Ni(pyNO)Cl2H2O (I), (pyNO=pyridine N-oxide), Ni(2-MepyNO)Cl2·2H2O (II), Ni(3-MepyNo)Cl2·2H2O (III) and Ni(4-MepyNO)2Cl2·C2H5OH (IV). The heating of the compounds led first to the release of H2O molecules (or C2H5OH molecules), with the formation of Ni(pyNO)Cl2 (V), Ni(2-MepyNO)Cl2(VI), Ni(3-MepyNO)Cl2 (VII) and Ni(4-MepyNO)2Cl2 (VIII). In the next stage, decomposition of the heterocyclic liugands set in. The compositions and spectral and magnetic properties of these complexes indicate their dimeric (II, III, IV, VIII) of polymeric (I, V, VI, VII) structure with coordinated molecules of H2O (or C2H5OH).
