In this paper, the reaction of 2-thioxoperhydro-1,3-thiazin - 4 ones; with VO(IV), Cr(III), Mn(II), Fe(II) and Fe(III) ions lead to the formation of M(TP)-x (H2O)y [M=Mn(II), Cr(III), Fe(III); x=1 or 2; y=2 or 3], VO(TP)2 and [Fe(TPH)CI2(PPh 3)2]. These complexes have been characterized by analytical, magnetic, thermogravimetric and spectral (IR, UV and Visible) studies and their tentative structures are proposed. Source

Nitrosyl complexes which have both L=methyl cyanide and triphenylphosphine as coexisting ligands were synthesized and characterised as cis [Ru(NO)(X)L 2(PPh 3) 2] +2 X=OH,Cl,NO 2 and L=CH 3CN). The structures of the complexes have been proposed on the basis of analytical, magnetic and spectroscopic (IR, UV-Visible and 1H NMR) methods. The properties of these complexes were investigated under the conditions of chemical oxidation and electrochemical reduction. Source

In this paper, the reactions of [M(PEt3)4] (M=Ni, Pd, and Pt) were Carried out with N-PhenylCarbonylPyrrole-2-thiocarboxamide (ETH) and N-Phenylcarbamoylpyrrole-2-thiocarboxamide (PTH). The product of the these reactions were characterized on the basis of analytical, spectral (IR, UV and Visible) and magnetic studies. A tentative structure has been proposed to these complexes.
