Supramolecular self assembly of a monomeric copper(II) complex of N-salicylidene-2-methoxyaniline forming three-dimensional closed and open channels

A binary copper(II) complex [CuL2] (1), where HL is the Schiff base N-salicylidene-2-methoxyaniline, was prepared and structurally characterized. The complex which crystallizes in cubic space group Ia-3d with an unit cell dimension of 31.2451(17) Å, V=30503(3) Å3, Z=48, and refined to R-value of 0.0379 for 1700 data with I>2σ(I), shows a distorted four coordinate structure with a CuN2O2 chromophore. The complex self-assembles into a supramolecular architecture by non-covalent C–H⋯O interactions forming open and closed channels.
