103. +, the arm of the ligand attached to Mn(2) is disordered over two conformations with occupancies of 0.692(5) and 0.308(5). Thus some of these differences in the coordination sphere about Mn(2) may be caused by this disorder. All tables include only parameters from the major conformation. The supplementary data contain the complete list of all parameters.
