Abstract: The title compound, [Ni(C₂H₅N₄S)₂], has a twofold axis. The Ni^II atom is coordinated in a deformed square-planar geometry by four imino N atoms of two atu ligands (Hatu = amidinothiourea). Two six-membered chelate rings including the Ni atom are twisted with a dihedral angle of 17.24  (16)°. The [Ni(atu)₂] units make a two-dimensional layer via N-HS hydrogen bonds.
