N2 - The crystal structure of the title compound has been determined by Patterson and Fourier methods from single-crystal X-ray diffractometer data, and refined by least squares to R 0.096 (2704 reflections). Crystals are triclinic, probable space group P1, a = 19.763(4), b = 9.563(2), c = 8.537(1) Å, α = 95.96(1), β = 93.48(1), γ = 94.44(1)°, Z = 2. Within the cation, each terpyridyl ligand co-ordinates via the three nitrogen atoms, the central Co-N distance being shorter than the outer [〈Co-N〉, 1.89, 2.10(1) Å respectively] and the ligand being strained to accommodate the bonding; the overall cation symmetry is approximately D2d. The bromide ions are disordered between lattice sites ca. 2.0 Å apart; the potential barrier between the two sites appears small and may be the determinant of the 'crossover' situation which exists in this complex.
