title: Aqua-(2,9-dimethyl-1,10-phenanthroline-κN,N')bis-(2-hydroxy-benzoato-κO)manganese(II) 2,9-dimethyl-1,10-phenanthroline hemisolvate.
abstract: In the asymmetric unit of the title complex, [Mn(C(7)H(5)O(3))(2)(C(14)H(12)N(2))(H(2)O)]·0.5C(14)H(12)N(2), the Mn(II) ion is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) mol-ecule, one water mol-ecule and two monodentate 2-hydroxy-benzoate anions in a distorted trigonal-bipyramidal geometry. The OH group of the 2-hydroxy-benzoate anion is disordered over two positions with site-occupancy factors of 0.5. The asymmetric unit is completed with by an uncoordinated half-mol-ecule of dmphen, disordered about a crystallographic twofold axis. In the crystal structure, mol-ecules are linked into a two-dimensional framework by O-H⋯N, O-H⋯O and C-H⋯O hydrogen bonds. The packing of the structure is further stabilized by π-π stacking inter-actions involving dmphen mol-ecules, with centroid-centroid separations of 3.8027 (3) and 3.6319 (3) Å.
