In the title compounds, [CuII(2-brpy)2(NO3)2] and [CuII(2-Clpy)2(NO3)2], the CuII atoms are each in a distorted square-pyramidal environment, in which four O atoms from the four bridging copper ligand form the basel plane and the pyridine N atoms. The two bromopyridine and Chloropyridine are nearly coplanar, making a dihedral angle of 23.1(6)° for compound and for compound 4.4 (6)°. In the compund (I), molecules are linked by N-O...π interactions, leading to the formation of zigzag chains along . In the crystal of (II), molecules are linked by C-H…O hydrogen bonds, forming chains along . The chains are linked by C-H…O hydrogen bonds, forming layers parallel to (101). Within the layer there is C-H…π interactions present.
