Dichlorido(2,9-diprop-oxy-1,10-phenanthroline-κN,N')cadmium(II).

In the title complex, [CdCl(2)(C(18)H(20)N(2)O(2))], the Cd(II) ion is coordinated by two N atoms from a bis-chelating 2,9-diprop-oxy-1,10-phenanthroline ligand and two Cl atoms in a distorted tetra-hedral environment. The two Cd-Cl bond distances are significantly different from each other and the N-Cd-N bond angle is acute. In the crystal structure, there are π-π stacking inter-actions between symmetry-related phenanthroline ring systems, with a centroid-centroid distance of 3.585 (3) Å.

catena-Poly[[(2,9-dieth-oxy-1,10-phen-anthroline-κN,N')cadmium(II)]-di-µ-dicyan-amido-κN:N].

In the title polymer, [Cd(C(2)N(3))(2)(C(16)H(16)N(2)O(2))](n), the Cd(II) ion is coordinated by two N atoms from one 2,9-dieth-oxy-1,10-phenanthroline mol-ecule and four N atoms from four symmetry-related dicyanamide ions in a distorted octa-hedral geometry. In the 2,9-dieth-oxy-1,10-phenanthroline ligand, the O and C atoms of the eth-oxy groups are located almost in the plane defined by the phenanthroline ring system. Two dicyanamide ions bridge two Cd(II) ions, which are located on a twofold axis, forming a one-dimensional zigzag chain along the [001] direction. The 2,9-dieth-oxy-1,10-phenanthroline mol-ecules act as bidentate terminal ligands. There are π-π inter-actions between polymeric chains, characterized by a centroid-centroid distance of 3.7624 (2) Šbetween the phenanthroline rings of two neighbouring chains.
