Bis[μ-2-(2-pyridylmethylaminomethyl)phenolato]-κ⁴N,N′,O:O;κ⁴O:N,N′,O-bis[(thiocyanato-κN)copper(II)]

Abstract

The centrosymmetric binuclear complex, [Cu2(C13H13N2O)2(NCS)2], formed via phenolate oxygen bridges, involves the CuII atoms in a distorted square-pyramidal coordination [τ = 0.197 (1)]. A Cu⋯Cu separation of 3.2281 (3) Å is observed. The in-plane Cu—Ophenolate distance [1.9342 (8) Å] is shorter than the axial distance [2.252 (8) Å]. The Cu—Namine and Cu—Npy distances are similar [2.0095 (10) and 2.0192 (10) Å, respectively]. The Cu—Nthio­cyanate distance [1.9678 (11) Å] is in the range found for Cu—N distances in previously determined structures containing coordinated thio­cyanate anions. There is an inter­molecular hydrogen bond between the amine H atom and the S atom of a coordinated thio­cyanate anion.

Magnetostructural Properties of Some Doubly-Bridged Phenoxido Copper(II) Complexes

“…Different strategies have been employed in the design of this class of compounds. The first approach was achieved though the interaction Cu(II) salts with tridentate ligand-based phenolates in their skeletons [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ], and the second approach was via the design of bicompartmental phenolates bearing two pendent arms of N-donor groups [ 1 , 2 , 3 , 4 , 5 , 6 , 42 , 43 ]. A third approach was also used through the design of tripodal pyridyl tetradentate ligands containing one or two phenolate arms [ 12 , 14 , 15 , 20 , 29 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ].…”
