“…Some Schiff bases are used as ion-selective electrode [8]. Some complexes containing nitrogen and oxygen donor atoms in the complexes are effective as stereospecific catalysts for oxidation, reduction, hydrolysis, biological activity and other transformations of organic and inorganic chemistry [9][10][11][12]. It is known that Schiff bases containing electroactive imine group in non-aqueous media have two reduction peaks corresponding to a one-electron transfer in a cyclic voltammogram and the electrode reaction is an EC mechanism [13].…”

A new Schiff-base complex 2-{(E)-[2-hydroxyphenyl)imino]methyl}phenol has been synthesized and characterized by elemental analyses, UV-VIS and IR spectroscopy and single crystal X-ray determination. The structure comprises two independent and similar molecules. The two independent molecules in the asymmetric unit are hydrogen bonded and have different conformations. In each molecule, C 13 H 11 NO 2 , adopt an E configuration about the azomethine C-N double bond. The complex crystallized in the triclinic space group P-1. Two benzene rings and azomethine group are practically coplanar, as a result of intramolecular hydrogen bonds involving the hydroxy O atom and azomethine N atom. Also hydroxy group of the molecule is the presence intermolecular O-HÁÁÁO hydrogen bonds with the hydroxy group of the other molecule.

“…Because of variable bonding modes, biological implications, and structural diversity of thiosemicarbazones [14][15][16], they have been used as drugs and are reported to possess a wide variety of biological activities against bacteria, fungi, and certain types of tumor [17,18]. It has been reported that the presence of bulky groups at N4 of the thiosemicarbazone moiety greatly enhances biological activity [19].…”

(E)‐2‐[2‐(1‐Substituted ethylidene)hydrazinyl]‐5‐oxo‐9b‐hydroxy‐5,9b‐dihydroindeno[1,2‐d][1,3]‐thiazine‐4‐carbonitriles and (E)‐5‐oxo‐[(E)‐(1‐substituted ethylidene)hydrazinyl]‐2,5‐dihydroindeno[1,2‐d][1,3]thiazine‐4‐carbonitriles have been obtained from the reaction of 2‐(substituted ethylidene)hydrazinecarbothioamides with 2‐(1,3‐dioxo‐2,3‐dihydro‐1H‐inden‐2‐ylidene)propanedinitrile (1) in ethyl acetate solution. However, (Z)‐6′‐amino‐1,3‐dioxo‐3′‐substituted‐2′‐[(E)‐(1‐phenylethylidene)hydrazono]‐1,2′,3,3′‐tetrahydrospiro(indene‐2,4′‐[1,3]thiazine)‐5′‐carbonitriles were observed during the reaction of N‐substituted‐2‐(1‐phenylethylidene)hydrazinecarbothioamides with (1). The structure assignment of products has been confirmed on the basis of 1H‐, 13C‐NMR, and mass spectrometry, as well as theoretical calculations.

This article presents a combined experimental and computational study of Ru(II) complex containing 2,5-pyridinedicarboxylic acid ligand. The novel complex [Ru(py-2,5-COOH) 2 (PPh 3 ) 2 ]Á3H 2 O has been obtained in the reaction of [RuCl 2 (PPh 3 ) 3 ] with 2,5-pyridinedicarboxylic acid in methanol and has been studied by IR, 1 H, 31 P NMR, UV-Vis spectroscopy, and X-ray crystallography. The electronic structure of [Ru(py-2,5-COOH) 2 (PPh 3 ) 2 ] has been calculated with the density functional theory (DFT) method. The spin-allowed electronic transitions of the complex have been calculated with the time-dependent DFT method, and the UV-Vis spectrum has been discussed on this basis and rationalized by determination of ligand field splitting (10Dq) and Racah's parameters from the experimental spectrum. The luminescence property of the complex has been examined.
