A. Castineiras et al., STEREOCHEMISTRY OF COPPER(II) COMPLEXES OF 1-(PYRIDINE-2-YL)-3-METHYL-3,6-DIAZAHEPTANE (PDAHP) - CRYSTAL-STRUCTURES OF CU(PDAHP)X(2) (X=CL,BR, NO3), Polyhedron, 13(3), 1994, pp. 435-440
The crystal structures of isotypical compounds Cu(PDAHP)X(2)]PDAHP = 1
-(pyridine-2-yl)]-3-methyl-3,6-diazaheptane, X = Cl, Br or NO3] which
have previously been spectroscopically studied, are reported. The ster
eochemistry of the three complexes is described on the basis of pentac
oordinate complexes of the type Cu(tridentate ligand) (unidentate liga
nd)(2). Distortions of the coordination polyhedra were calculated by t
he Muetterties and Addison methods and the results obtained are discus
sed.
