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

ABSTRACT: 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].

Project description:In the title compound, [CdI(2)(C(14)H(12)N(2))], the mol-ecule sits on a crystallographic twofold axis.
