 Title    Reactions of Chromyl Chloride with Carboxylic Acids and Carboxylic Acid Anhydrides  
 Abstract    Chromyl Chloride reacts with carboxylic acids [RCOOH where R — C2H5, AZ-C3H7, CH2CI, CHC1 2 and CCI3] to give reduced chromium(III) carboxylates, [Cr 3 0(00CR) 6 (H 2 0) 3 ]Cl. Magne-tic susceptibility, UV-visible and IR measurements are all consistent with their trinuclear basic structures. Reactions of chromyl chloride with carboxylic acid anhydrides [(RCO) z O where R = CH 3 , C 2 H 5 and «-C 3 H 7 ] give dinuclear oxo-bridged complexes of the type, [Cr 2 0(00CR) 3 ]Cl. These compounds behave as non-electrolytes in polar organic solvents. IR spectra suggest the presence of bridging carboxylato groups containing Cr—O — Cr chains. Their low magnetic mo-ment values suggest polymeric structures exhibiting antiferromagnetic coupling between Cr atoms.
