Resumen:
The title compound crystallizes in the orthorhombic space group Pnma, with a = 7.9209(5), b = 9.818(1), c = 16.867(2) A, and Z = 4. The structure was solved employing 1864 independent x-ray reflections with I > 2a(I) by Patterson and difference Fourier techniques and refined by full-matrix least-squares to R = 0.036. The trans-[CO(NH3)4(NH2CH3)Cl](ClO4)2 molecule is on a crystallographic mirror plane. The cobalt ion is in an elongated octahedral coordination with four equatorial ammonia ligands [average CoN distance equal to 1.966(2) A], an axial methylamine [Co-N = 1.965(3) A] and an axial chlorine ion [Co-Cl = 2.2771(9) A]. Kinetic steric effects of the complex are interpreted in terms of structural results.
