Dobrzariska L. (2005)


In the title compound, [Cr(CO3)(C16H 36N4)]Br-H2O, the chromium cation has a distorted octahedral geometry with ligation provided by the four N atoms of the 'folded' macrocyclic ligand and by two O atoms of the bidentate carbonate anion. Two neighbouring chromium complexes are bridged by two strong N-H⋯O hydrogen bonds to form dimeric units which, in turn, are constituents of infinite chains formed by virtue of three other types of hydrogen bonds (N -H⋯Br, N - H⋯Ow and Ow - H⋯Br). © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
