In the title compound, [Co(NCS)(2)(C(11)H(13)NO(2))(2)], a mononuclear Schiff base cobalt(II) complex, the Co atom is six-coordinated by four O atoms from two Schiff base ligands, and by two N atoms from two thio-cyanate ligands, forming a distorted octa-hedral geometry. The central Co atom lies on a twofold rotation axis. An intramolecular N-H⋯O hydrogen bond is present.

In the title complex, [Co(NCS)(2)(C(13)H(11)N(3)O)(2)], the Co(II) centre adopts a distorted octa-hedral coordination geometry with two cis-bidentate Schiff base ligands and two cis thio-cyanate ligands. The Schiff base ligand coordinates via the imine N and pyridine N atoms. The Co(II) atom lies on a crystallographic twofold rotational axis. Non-classical inter-molecular C-H⋯O hydrogen bonds l...

A series of symmetric multidentate Schiff base ligands 1–13 based on the N‚N′-4‚4′-ethylenebiphenylbis-3-methoxysalicylideneimine for used to bind various transition metals detection of K, AgI‚ CuII, Sr II Co II and NiII at trace levels in real-world samples has been synthesized purified and their structures was characterized.

Schiff base macrocycles are emerging as useful scaffolds for binding two or more catalytic metals in close proximity. Such coordination chemistry allows for the evaluation of potentially beneficial catalytic cooperative effects. In the field of ring opening polymerization (ROP) of cyclic esters, only a handful of metal systems bound by Schiff base [2 + 2] type macrocycles have been studied. Nev...
