All ligands are monodentate. The four O atoms around the Mn atom form a slightly distorted equatorial plane, while the distorted octahedral coordination is completed by the two N atoms in the axial positions. An intramolecular O-H center dot center dot center dot O hydrogen bond occurs in the complex. In the crystal structure, O-H center dot center dot center dot O hydrogen bonds link the molecules through an R-2(2)(16) ring motif, forming a one-dimensional chain along the a axis. The pi-pi contact between the pyridyl rings [centroid-centroid distance = 3.629 (2) angstrom] may further stabilize the structure.eninfo:eu-repo/semantics/openAccessArticle10.1107/S16005368090060472-s2.0-62149098394U85621582097Q3M32465WOS:000264796100067Q4
