Bis[-2-(2-pyridylmethylaminomethyl)phenolato]-k4 N,N′,O:O;k4 O:N,N′,O-bis-[(thiocyanato-N)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 [ = 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 - Nthio-cyanate distance [1.9678 (11) Å] is in the range found for Cu - N distances in previously determined structures containing coordinated thio-cyanate anions. There is an inter-molecular hydrogen bond between the amine H atom and the S atom of a coordinated thio-cyanate anion. © Assey et al. 2009.
