摘要：

The complexes bis(6,6'-dibromo-2,2'-bipyridine-N,N')copper(I) perchlorate, [Cu(C10H6Br2N2)(2)]ClO4, and bis(6,6'-dibromo-2,2'-bipyridine-N,N')silver(I) tetrafluoroborate, [Ag(C10H6Br2N2)(2)]BF4, both contain four-coordinate pseudo-tetrahedral metal centres, in which the two bidentate chelating ligands are nearly mutually perpendicular; the average dihedral angle between the two MN2 planes is 87.9 degrees for M = Cu but only 75 degrees for M = Ag, which reflects the lesser inter-ligand steric interactions in the silver(I) complex, arising from the greater metal-ligand bond distances. For both complexes, the crystal packing is dominated by intermolecular Br ... Br interactions.
