Tris[2,4-dichloro-6-(ethyl­imino­meth­yl)phenolato-κ²N,O]cobalt(III)

The asymmetric unit of the title compound, [Co(C₉H₈Cl₂NO)₃], contains three independent mol­ecules. In each mol­ecule, the Co^III ion is coordinated by an O atom and an N atom from three bidentate 2,4-dichloro-6-(ethyl­imino­meth­yl)phenolate ligands in a slightly distorted octa­hedral environment. In the crystal, a weak C—H...Cl hydrogen bond is observed.

trans-Bis[4-amino-N-(pyrimidin-2-yl-κN)benzene­sulfonamidato-κN]bis(N,N-dimethyl­formamide-κO)cobalt(II)

The title complex, [Co(C₁₀H₉N₄O₂S)₂(C₃H₇NO)₂], lies across an inversion center. The Co^II atom is coordinated in a slightly distorted octa­hedral geometry by four N atoms from two bidentate 4-amino-N-(pyrimidin-2-yl)benzene­sulfonamidate (sulfadiazine) anions and two O atoms from two dimethyl­formamide (DMF) ligands. The dihedral angle between the benzene and pyrimidine rings is 82.37 (13)°. A three-dimensional network is generated by N—H...O hydrogen bonds between the amino groups and of the sulfonamidate O atoms of neighbouring mol­ecules. The DMF ligand is disordered over two sets of sites in a 0.559 (4):0.441 (4) ratio.
