“…The electronic re¯ectance spectrum of (I) involves a single broad peak at 13 850 cm À1 , corresponding to an elongated tetragonal octahedral geometry with off-axial-direction coordination from the normal to the N1/N2/O2/Cl1 plane (Procter et al, 1972). The electronic spectrum of (I) is similar to those found in complexes with similar Cu II (Youngme et al, 2006). The symmetric and antisymmetric NO stretchings appear as strong bands at 1310 and 1384 cm À1 , respectively, consistent with the asymmetric bidentate nitrate group (Lewis et al, 1972).…”

“…[CuCl(O 2 CCH 3 )-(dpyam)] (Ugozzoli, et al, 1997) and [CuCl(O 2 CCH 2 CH 3 )-(dpyam)]ÁH 2 O (Youngme et al, 1999), which comprise mononuclear units with bidentate acetate or propionate ligands and, in the latter, an uncoordinated water molecule, giving a distorted square-based pyramidal geometry. The most similarity to compound (I) is found in the square-pyramidal complex [Cu(NCS)(O 2 CCH 3 )(dpyam)(H 2 O)] (Youngme et al, 2006), containing a pseudohalide, a coordinated water molecule and a monodentate acetate ligand. The second O atom of the acetate anion coordinates to the Cu II ion in a similar fashion to that of the nitrate in compound (I), but with a very long CuÐO distance [3.064 (1) A Ê ].…”
