title: Bis[2,3,4-trimethyl-5-[(3,4,5-trimethyl-2H-pyrrol-2-yl-idene-κN)meth-yl]-1H-pyrrolato-κN]copper(II).
abstract: In the title complex, [Cu(C(15)H(19)N(2))(2)] or [Cu(L(2))] (HL is 3,3',4,4',5,5'-hexa-methyl-pyrromethene), 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 tetra-hedral geometry. The mean planes of the CuN(2)C(3) 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 inter-molecular C-H⋯π inter-actions, which form chains in [100].
