Abstract
The crystal and molecular structure of chloro-{6S, 15S-(4R,13R-dimethyl)-1,5,10.14-tetraazatricyclo[13,3,1,16,10]eicosane}copper(II)perchlorate, [Cu(S-mac6)C1O4, been determined by X-ray analysis. Crystal data: C18H36N4O4C12Cu is orthorhombic, space group P212121, a = 11.915(2), b = 12.290(2), c = 15.705(6) Z = 4. The structure was refined by full-matrix least-squares procedures to R = 0.040 for 2477 unique non-zero (I > 1.5s(I)) reflections and with h = 1.02(7) confirming the absolute configurations of the chiral centres. The N4 macrocycle coordinates to the copper atom in a swuare-planar arrangement with Cu-Nsec of 2.005(5) and Cu-Ntert of 2.0960(4) , and a square-based pyramidal geometry is completed by a chloride ion, Cu-c1 2.711(2). Folding of the non-chelate six-membered rings produces a conformation such that only one face of the complex ion is available for axial coordination of unidentate ligands....
