Distorted octahedral coordination geometries based on a N2S4 donor set are found in each of the molecular structures of the title complexes Mn(S2COCH2CH3)(2) (1,10-phenanthroline) (1) and Mn(S2COCH2CH3)(2) (2,2'-bipyridyl) (2) Analyses of the geometric parameters indicate that the five-membered ring in (1) has significantly more aromatic character than the analogous ring in (2) In terms of coordination of the xanthate ligands, one ligand in (1) is considerably more aromatic than the remaining ligands This latter feature allows for the formation of C-H pi (S2C) interactions leading to a supramolecular chain in (1) By contrast, in (2), the crystal packing is dominated by C-H O contacts, which lead to a supramolecular chain with 41 symmetry, which combine with C-H S contacts to consolidate the three-dimensional architecture Unit cell data for (1) hexagonal, space group (R) over bar3, a = 35 228(5) and c = 9 0086(13) angstrom, and for (2) tetragonal, space group 14(1)/a, a = 31 120(7) and c = 8 306(2) A
