Bis[N (3)-(2-hydroxy­benzo­yl)pyridine-2-carboxamidrazonato-κ(3) N (1),N (2),O]manganese(II)

In the title compound, [Mn(C(13)H(11)N(4)O(2))(2)], the Mn atom is coordinated in a distorted octa­hedral manner by pyridyl N atoms, amidrazonato N atoms and carbamoy O atoms from two tridentate N (3)-salicyloylpyridine-2-carboxamidrazonato ligands. N—H⋯O hydrogen bonds result in the formation of two chains, one parallel to the b axis and the other one parallel to the c axis. These two chains are cross-linked, building up layers parallel to the (100) plane.
