Abstract
In an effort to utilize the [Co(NH3)(6)](3+) cation as a new anion receptor (binding agent) for dihydroxy dicarboxylate anion i.e., tartrate, orange single crystals of hexaamminecobalt(III) chloride (R,R)-tartrate monohydrate, [Co(NH3)(6)]Cl(C4H4O6)center dot H2O, were obtained by reacting hexaamminecobalt(III) chloride with potassium-sodium tartrate tetrahydrate in a 1:1 molar ratio in hot water. The single crystal X-ray structure determination of [Co(NH3)(6)]Cl(Cl4H4O6)center dot H2O revealed that a distinctive network of hydrogen bonding interactions (N-H center dot center dot center dot O, N-H center dot center dot center dot Cl-, O-H center dot center dot center dot O) stabilize the crystal lattice. This is the first complex salt of hexaamminecobalt(III) with dihydroxy dicarboxylate anion i.e., tartrate. (c) 2006 Elsevier B.V. All rights reserved.
