Abstract
Crystalline ternary mixed aminopyridine complexes of cobalt(II) chlorides and cobalt(II) bromides have been prepared and analysed by means of thermal (TG, DTG, DTA) methods, UV/VIS spectroscopy, magnetic measurements and X-ray powder diffraction techniques. The symmetry and cell dimensions have been calculated using TREOR 90, a trial-and-error indexing program. One of the compounds, namely the [Co(3-NH2-pyridine)4Cl2] complex has been studied also by X-ray single-crystal diffraction, yielding a propeller-shaped molecule with octahedral co-ordination, exhibiting both molecular and crystallographic inversion symmetry. Crystal data: C20H24N8Cl2Co, Mw = 506.30, triclinic (P-1) unit cell with a = 7.684(1), b = 8.582(1), c = 9.966(2) Å, α = 73.17(1), β= 69.97(1), γ = 70.33(1)°, Vc = 570.0(2) Å3 and Z = 1. The structure model was refined to R = 0.027 and wR = 0.037 for 2680 reflections with I > 3σ(I).
