Acid-stable macrocyclic complexes of chromium(II) are rare. The trans-Cr((14)aneN{sub 4})(H{sub 2}O){sub 2}{sup 2+} complex ((14)aneN{sub 4} = 1,4,8,11-tetraazacyclotetradecane, hereafter L) is exceptional in this respect. However, the synthetic routes to its immediate precursor, trans-CrL(H{sub 2}O){sub 2}{sup 3+}, that were available until now are laborious, and the isolation of the solid perchlorate salt is outright dangerous. Here the authors report a simple, one-step synthesis of trans-(CrLCl{sub 2})Cl and its safe and easy conversion to trans-(CrL(H{sub 2}O){sub 2})(CF{sub 3}SO{sub 3}){sub 3}.
