AbstractN,N′-ethylene-bis-(tetronic-acid-3-formiminato)-copper(II)/K1 crystallizes in space groupN,N′-ethylene-bis-(tetronic-acid-3-formiminato)-nikkel(II)/K2 crystallizes in space groupN,N′-ethylene-bis-(1,5,5-trimethyltetramic-acid-3-formiminato)-copper(II)/K3 crystallizes in space groupIn K1 and K3 copper is coordinated by two nitrogen and two oxygen atoms of the ligand molecule as well as by one water molecule on top of a tetragonal pyramid. In K2 two water molecules are included in the complex formation. These and two nitrogen as well as two oxygen ligand atoms form a nearly regular octahedron.
