3,9-DIMETHYL-4,8-DIAZA-3,8-UNDECADIENE-2,10-DIONE DIOXIMATO(1-)(THIOCYANATO)-COPPER(II) AND 3,6,6,9-TETRAMETHYL-4,8-DIAZA-3,8-UNDECADIENE-2,10-DIONE DIOXIMATO(1-)(ISOTHIOCYANATO)COPPER(II)

摘要

[[abstract]]The coordination geometries about the Cu-II ions in both [3,9-dimethyl-4,8 -diaza-3,8-undecadiene-2,10-dione dioximato(1 -)](thiocyanato)copper(II), [Cu(C-11-H19N4O2)(SCN)] (1) and [3,6,6,9-tetramethyl-4,8 -diaza-3,8-undecadiene-2,10-dione dioximato(1 -)](isothiocyanato)copper(II), [CU(C13H23N4O2)(NCS)] (2), are distorted square pyramidal with the four diazadioxime N atoms in equatorial positions and the monodentate ligand axial. This monodentate axial ligand is an S-bonded thiocyanato group in complex (1) and an N-bonded isothiocyanato group in (2). The intramolecular O O hydrogen-bond lengths are 2.530(4) and 2.490(2) Angstrom in complexes (1) and (2), respectively.
