Abstract

Cobalt (III) complexes with N-salicylidene-2-hydroxy-5-bromobenzylamine (H2sbba) and N-salicylidene-2-hydroxy-5-chlorobenzylamine (H2scba), [n-(C4H9)4N][Co(sbba)2] (I) and [n-(C4H9)4N][Co(scba)2] (II), were synthesized. The crystal structure of II was determined by the single-crystal X-ray diffraction method at 90 K confirming its crystallization in the monoclinic space group P21/n with a = 11.729(2) Å, b = 16.901(3) Å, c = 21.483(4) Å, β = 98.840(4)°, V = 4208.2(14) Å3, Dx = 1.295 g cm−3, and Z = 4. The R1 [I > 2σ(I)] and wR2 (all data) values of 0.0664 and 0.1920, respectively, for all 9521 independent reflections. The compound is composed of a tetra(n-butyl)ammonium cation and an octahedral cobalt(III) complex anion with two scba2− ligands in a meridional fashion. The electronic spectral features of I and II are consistent with the octahedral cobalt(III) ion with an N2O4 donor set.
