bipyramids fused about a common iron apical vertex and sharing a double-capping BH function. Crystals are orthorhombic, space group P212121 with a= 16.533(5), b= 11.012(2), c= 16.279(3)Å, and four molecules per unit cell. Using 3 496 amplitudes recorded on a four-circle diffractometer at 291 ± 1 K the structure has been refined to R 0.043. The Co–Fe distance is 2.5300(8)Å; 0.05 Å longer than that in
