Dibromido(2,9-dimethyl-1,10-phenanthroline-?(2) N,N')(dimethyl sulfoxide-?O)cadmium.

ABSTRACT: In the mol-ecule of the title compound, [CdBr2(C14H12N2)(C2H6OS)], the Cd(II) atom is five-coordinated in a distorted trigonal-bipyramidal configuration by two N atoms from a 2,9-dimethyl-1,10-phenanthroline ligand, one O atom from a dimethyl sulfoxide ligand and two Br atoms. In the crystal, ?-? contacts between the pyridine and benzene rings [centroid-centroid distances = 3.710?(5), 3.711?(6) and 3.627?(5)?Å] stabilize the structure.

Project description:In the title complex, [CdBr(2)(C(14)H(12)N(2))], the Cd(II) ion is tetra-coordinated by two N atoms of the bidentate 2,9-dimethyl-1,10-phenanthroline ligand and two bromide ions in a substanti-ally distorted CdN(2)Br(2) tetra-hedral geometry. In the crystal, inversion dimers linked by pairs of weak C-H?Br bonds generate R(2) (2)(14) loops. Aromatic ?-? stacking [shortest centroid-centroid separation = 3.633?(2)?Å] inter-actions occur within, and also link, the dimers into chains propagating parallel to [100].

(2,9-Dimethyl-1,10-phenanthroline-?N,N')diiodidocadmium.

Project description: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 by ?-? stacking inter-actions between the phenanthroline ring systems, with centroid-centroid distances of 3.707?(9) and 3.597?(10)?Å.

Project description:In the title compound, C16H8N6O2S2·2C2H6OS, the phenanthroline mol-ecule resides on a twofold axis, and the asymmetric unit also contains a slightly disordered [occupancy ratio for S atom of 0.95 (3):0.047 (3)] mol-ecule of dimethyl sulfoxide.
