catena-Poly[[(1,10-phenanthroline-²N,N')cadmate(II)]-di--bromido]

B.-S. Zhang

Abstract: The title compound, [CdBr₂(C₁₂H₈N₂)]_n, is a 1:1 adduct of cadmium bromide with 1,10-phenanthroline (phen), which contains an infinite chain consisting of Cd₂Br₂ parallelograms sharing the Cd coners. The chain propagates along the c axis. Both the Cd^II atom and the phen molecule lie on a twofold rotation axis. The Cd^II atom is coordinated by two N atoms from a chelating phen ligand and four Br atoms to complete a distorted octahedral geometry. The closest atom-to-atom distance of 3.35 (1) Å between the phen ligands of two adjacent chains indicates the existence of - interactions, which result in a two-dimensional layer parallel to the bc plane. The layers are associated through weak C-HBr hydrogen bonds.
