Stereochemistry of rigid chelate–metal complexes. Part I. The crystal structure of dichloro-(2,9-dimethyl-1,10-phenanthroline)zinc(II)

Dibromido(2,9-dimethyl-1,10-phenanthroline-κ2N,N′)cadmium

“…The Cd II cation is located on a general position in a tetrahedral environment built up from two nitrogen atoms (N1, N2) of one dmphen bidentate ligand and two bromide ions (Br1, Br2). Similar coordination geometry around the central atom has been observed in other metal complexes involving the same ligand (dmphen) such as [HgBr 2 (dmphen)], (Alizadeh et al, 2009), [ZnCl 2 (dmphen)] (Preston et al, 1969), [CuCl 2 (dmphen)] (Wang et al, 2009).…”

(2,9-Dimethyl-1,10-phenanthroline-κ2N,N′)diiodidocadmium

“…Geometrical analysis of the bond lengths and angles around the cadmium atom, Cd-N = 2.305 3 (Alizadeh et al, 2009), [ZnCl 2 (dmphen)], (Preston & Kennard, 1969), [CuCl 2 (dmphen)] (Wang et al, 2009). The phenyl and pyridyl rings of dmphen ligand are planar with a mean atomic deviation of 0.011 Å and 0.013 Å respectively.…”
