Tetrakis[μ-1,4-bis(4,5-dihydro-1,3-oxazol-2-yl)benzene-κ2 N:N′]tetrakis(μ-methanolato-κ2 O:O)bis(μ-perchlorato-κ2 O:O′)tetracopper(II) bis(perchlorate)

The title tetranuclear CuII complex, [Cu4(C12H12N2O2)4(CH3O)4(ClO4)2](ClO4)2, is located around an inversion center. Each CuII atom is coordinated by two cis-O atoms from two bridging methanolate anions and two cis-N atoms from two bridging 1,4-bis(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands...

Each CuII atom is coordinated by two cis-O atoms from two bridging methanolate anions and two cis-N atoms from two bridging 1,4-bis(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in the basal plane, and is further coordinated by one O atom of the bridging perchlorate anion, forming a distorted square-pyramidal geometry. The Cu⋯Cu separations in the rectangular core are 2.9878 (11) and 6.974 (1) Å. In the asymmetric unit, there are two L ligands with a syn conformation. In one L ligand, the dihedral angles between the central benzene ring and the terminal 4,5-dihydro-1,3-oxazol-2-yl mean planes are 22.1 (4) and 33.1 (4)°, and in the other L ligand the corresponding dihedral angles are 29.3 (4) and 29.9 (4)°. The uncoordinated perchlorate anion is linked with the complex molecules via weak C—H⋯O hydrogen bonds.
