Dimeric (2-cyano-phenolato-κO){2,2'-[ethyl-enebis(nitrilo-methyl-idyne)]diphenolato-κO,N,N',O'}manganese(III) monohydrate.

The molecules of the title compound, [Mn(C(7)H(4)NO)(C(16)H(14)N(2)O(2))]·H(2)O, form dimers in the solid state across a crystallographic inversion center. The bridging Mn(2)O(2) group is built of phen-oxy groups, and is asymmetric, with an Mn-O distances of 1.9002 (13) and 2.6236 (14) Å. A substantial cavity between the two Mn atoms [Mn⋯Mn = 3.5082 (4) Å] is produced by the formation of the dimer. In the crystal, an extended network of O-H⋯O hydrogen-bonding inter-actions stabil-izes the structure.
