Hydrothermal synthesis of chiral inorganic-organic CoII complex: Structural, thermal and catalytic evaluation

By heating the cobalt chloride hexahydrate (CoCl·6HO) with the R form of the organic amine α-methylbenzylamine (CHN) under hydro(solvo)thermal conditions, we have successfully generated the corresponding non-centrosymmetric homochiral hybrid tris (α-methylbenzylammonium tetrachloridocobaltate chlori...
