Chloridobis(ethane-1,2-diamine)(4-methylaniline)cobalt(III) dichloride monohydrate

Abstract

In the title compound, [CoCl(C2H8N2)2(C7H9N)]Cl2·H2O, the CoIII ion has a distorted octa­hedral coordination environment and is surrounded by four N atoms in an equatorial plane, with the other N and Cl atoms occupying the axial positions. The crystal packing is stabilized by N—H⋯O, N—H⋯Cl and O—H⋯Cl inter­actions.

Chloridobis(ethane-1,2-diamine-κ2 N,N′)(3-methylpyridine-κN)cobalt(III) dichloride monohydrate

“…The Co III cation is octahedrally surrounded by four N atoms of two ethane-1,2-diamine ligands, a pyridine N atom and a Cl À ligand, whereby the pyridine N atom and the Cl À ligand are cis to each data reports other. The Co-N and Co-Cl bond lengths are typical for trivalent cobalt and comparable with related complexes comprising of N-and Cl-donating ligands Ramesh et al, 2008;Ravichandran et al, 2009). The least-squares planes of the two ethane-1,2-diamine ligands make a dihedral angle of 78.0 (2) .…”

“…Trans -[Co(tn) 2 Br 2 ]Br, precursor complex was synthesized following the established procedure in the literature. 27–29 The cis -[Co(tn) 2 (Rpy)Br]Br 2 complexes were synthesized utilizing an simple mechanochemical approach from the precursor complex. To this end, one gram of trans -[Co(tn) 2 Br 2 ]Br was transformed into a paste using distilled water and subsequently ground with an equimolar amount of R -pyridyl (where R = 4-CN, H, 4-Bz, 4-Me, 4-Et, and 4-MeNH) for 3–5 hours.…”

Chloridobis(ethane-1,2-diamine)(4H-1,2,4-triazole-κN1)cobalt(III) dichloride

“…The title complex was synthesized by the reported method (Ravichandran et al, 2009) by taking 2 g of the trans-[Co III (en) 2 Cl 2 ]Cl complex and 0.5 g of 1,2,4-triazole. The cobalt(III) complex was recrystallized by addition of few drops of concentrated HCl in 10 ml of water containing 1 g of the complex.…”
