چکیده
The asymmetric unit of the title compound, [PtCl(3.66)I(0.34)(C(12)H(8)N(2))]·0.5(Cl(0.13)I(1.87)), contains a neutral Pt(IV) complex and one half of a halogen molecule. The Pt(IV) ion is six-coordinated in a distorted octa-hedral environment by two N atoms of the 1,10-phenanthroline ligand and Cl or I atoms. The refinement of the structure and the EDX analysis indicate that the compound is a solid solution in which there is some substitution of Cl for I and vice versa. The chemical formula of the pure state of the compound would have been [PtCl(4)(C(12)H(8)N(2))]·0.5I(2). In the analysed crystal, two Cl atoms are partially (ca 25% and 9%) replaced by I atoms, and the I(2) mol-ecule has a minor component modelled as ICl. As a result of the disorder, the different trans effects of the N and Cl/I atoms are not distinct. The complex displays inter-molecular π-π inter-actions between the six-membered rings, with a centroid-centroid distance of 3.771 (4) Å. There are also weak intra-molecular C-H⋯Cl hydrogen bonds.

The title complex, [Cu(C(3)H(2)N(3)O(2))Cl(C(12)H(8)N(2))], crystallizes with two independent mol-ecules in the asymmetric unit. Each Cu(II) atom is coordinated by an N atom and an O atom from the bidentate 1H-1,2,4-triazole-3-carboxyl-ate ligand, two N atoms from the 1,10-phenanthroline ligand, and the Cl atom. The coordination geometry is based on a ClN(3)O square pyramid. In the crystal stru...
