STRUCTURE OF (3RS,7SR)-3,7-DIMETHYL-3,7-DIAZANONANE-1,9-DIAMINE-PERCHLORATOCOPPER(II) PERCHLORATE, CU(CLO4)(C9H24N4)(CLO4)

摘要

[[abstract]]The Cu(II) is coordinated in a slightly distorted square pyramid with the four N atoms equatorial and the O atom of the perchlorate group axial. The four donor N atoms are coplanar; Cu(II) is 0.0165 angstrom out of this plane towards the perchlorate group. This complex has the (3RS,7SR) configuration at the chiral N centers, with the two N-methyl groups on the same side of the plane of the four N atoms. The tetraamine binds to the Cu(II) atom in a relatively strain-free planar fashion; the central six-membered ring exhibits a stable chair form and the two terminal five-membered rings take stable skew forms.
