The asymmetric unit of the title compound, [MnCl2(C16H20N2O)4]·2C16H20N2O, is composed of two coordinating N-(adamantan-1-yl)pyridine-4-carboxamide mol­ecules, one Cl− anion, an MnII ion, lying on an inversion centre, and one free N-(adamantan-1-yl)pyridine-4-carboxamide mol­ecule. The distorted octa­hedral Mn environment comprises two terminal Cl atoms and four monodentate N atoms from four organic ligands. All the carbamoyl N atoms are involved in inter­molecular N—H⋯O hydrogen-bonding inter­actions which link the mol­ecules into a chain along the a axis.
