Abstract

In the title complex, [Mn(C(11)H(10)N(3)O(2))(2)]·2C(7)H(4)N(2)O(6), the Mn(II) atom has a disorted octa-hedral coordination formed by four N and two O atoms of two mer-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands (DMPP). Each of the two symmetry-independent 3,5-dinitro-benzoic acid mol-ecules is linked to the mol-ecule of the complex via a hydrogen bond involving its carboxylic H atom and one of the DMPP ligands of the complex. However, in one of the DMPP ligands, the non-coordinated carbonyl O atom serves as the hydrogen-bond acceptor, whereas in the second ligand it is the Mn-coordinated O atom which is involved in the hydrogen bonding.
