Abstract
The crystal structure of N,N′-dipyridyl-N,N′-ethylenedi(5-bromo-3-formyl-2-hydroxybenzylamine) was determined by single-crystal X-ray diffraction. The compound crystallizes in a monoclinic system and was characterized thus: C2/c, a = 17.6158(13), b = 9.2327(7), c = 17.6983(13)Å, β = 102.771(2)°, Z = 4, V = 2807.3(4)Å3. The crystal structure was solved by direct methods and refined by full-matrix least-squares on F2 to final values of R1 = 0.0557 and wR2 = 0.0648. The complex consists of monomeric units with a coordination sphere of CoN4O2 type. The geometry around cobalt(II) is distorted octahedral with two amine nitrogen donors, two cis-phenolic oxygen donors, and two trans-pyridine nitrogen atoms.
