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 betwee...

In the crystal structure of the title compound, [Mn(C5H7O2)2(C12H8N2)], the Mn(2+) cation is coordinated by one bidentate 1,10-phenanthroline ligand and two acetyl-acetonate anions within a slightly distorted N2O4 octa-hedron. The asymmetric unit consists of one Mn(2+) cation situated on a twofold rotation axis, one half of a 1,10-phenanthroline ligand and one acetyl-acetonate anion. In compari...

The constituents of the title 1:1 co-crystal, C(7)H(6)O(2)·C(14)H(12)N(2), are connected into dimeric aggregates by a bifurcated O-H⋯N hydrogen bond; the hydroxyl-H atom is hydrogen bonded to the two N atoms of the 2,9-dimethyl-phenanthroline. The hydrogen-bonded residues are almost orthogonal to each other [dihedral angle = 78.56 (7) °]. In the crystal packing, the aggregates are assembled int...

The asymmetric unit of the title compound, [Co(C(12)H(6)N(2)O(2))(H(2)O)(4)](NO(3))(2), consists of a Co(II) complex cation with twofold rotational symmetry and two nitrate anions. The Co(II) atom has a distorted octa-hedral geometry with the basal plane occupied by two 1,10-phenanthroline-5,6-dione N atoms and two aqua O atoms, with the other two aqua ligands in axial positions. The aqua ligan...

In the title compound, [Cu(C(8)H(7)O(2))(2)(C(12)H(8)N(2))], the Cu(II) atom assumes a distorted octa-hedral coordination geometry, chelated by two N atoms from the 1,10'-phenanthroline ligand and four O atoms from two 2-methyl-benzoate anions. A significant Jahn-Teller distortion is observed with two axial Cu-O distances significantly longer than those in the equatorial CuO(2)N(2) plane. In th...

In the title complex, [Cd(C(7)H(4)ClO(3))(2)(C(12)H(8)N(2))(2)], the Cd atom is coordinated by two 5-chloro-salicylate ligands and two 1,10-phenanthroline ligands, displaying a distorted octa-hedral coordination geometry. The crystal structure is stabilized by O-H⋯O and C-H⋯O hydrogen bonds and π-π inter-actions between the 1,10-phenanthroline ligands and 5-chloro-salicylate ligands, with a cen...

All non-H atoms except for the Cl atoms lie on a mirror plane in the title complex, [ZnCl(2)(C(16)H(16)N(2)O(2))]. The Zn(II) ion is coordinated by two N atoms from a bis-chelating 2,9-dieth-oxy-1,10-phenanthroline ligand and two symmetry-related Cl atoms in a distorted tetra-hedral environment. The two Zn-N bond lengths are significantly different from each other and the N-Zn-N angle is acute....

A series of calculations on the energetics of complexation of alkaline metals with 1,10-phenanthroline are presented. It is an experimental fact that the ordering of the free energy of transfer across the water 1,2-dichloroethane interphase is governed by the charge / size ratio of the diferent cations; the larger cations showing the lower free energy of transfer. This ordering of the free ener...

In the title compound, [CdI(2)(C(14)H(12)N(2))], the mol-ecule sits on a crystallographic twofold axis. The coordination sphere of the Cd(II) atom is built of two symmetry-equivalent N atoms of one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and two symmetry-equivalent I atoms, thus forming a distorted tetra-hedral geometry. Inversion-related mol-ecules inter-act along the c-axis direction...
