Abstract: In the title complex, [Cu(C₁₅H₁₉N₂)₂] or [Cu(L₂)] (HL is 3,3',4,4',5,5'-hexamethylpyrromethene), the Cu^II atom is coordinated by four N atoms [Cu-N 1.939 (2)-1.976 (2) Å] from two L ligands in a distorted tetrahedral geometry. The mean planes of the CuN₂C₃ metallocyclic rings form a dihedral angle of 72.73 (6)°. In the L ligands, the pyrrole rings are inclined to each other at dihedral angles of 3.03 (7) and 9.83 (7)°. The crystal packing exhibits weak intermolecular C-H interactions, which form chains in [100].
