摘要:
The crystal structure of [Cu(NCS)(2)(N,N,N',N'-tmen)-(H2O)] (N,N,N',N'-tmen is N,N,N',N'-tetramethylethylenediamine, C6H16N2) consists of discrete non-centrosymmetric molecules connected by a network of OH ... S hydrogen bonds. The coordination polyhedron around the Cu-II atom is square pyramidal, with the Cu atom about 0.22 Angstrom above the plane of the four N atoms. The Cu-N basal-plane bond length has a mean value of 1.9999 Angstrom. The fifth (apical) position is occupied by the O atom of the water molecule [Cu-O 2.342 (3) A]. The N,N,N',N'-tetramethylethylenediamine chelate ring displays an unsymmetrical 'gauche' configuration.
