Crystal Structure of Bis[3-hydroxy-N′-(propan-2-ylidene)naphthalene-2-carbohydrazido]copper(II)

Abstract

The crystal structure of CuL₂ (HL = 3-hydroxy-N′-(propan-2-ylidene)-2-naphthohydrazide) was determined by an X-ray diffraction method. The coordination polyhedron around the copper(II) is better described as a elongated octahedron. The four-coordinated Cu(II)L₂ fragments are arranged via weak intermolecular Cu-O and C-H…π interactions; as a result, a 1D ladder type chain was constructed running along the a direction. Furthermore, 2D ladder type frameworks were facilitated by weak non-covalent interactions, such as C-H…O, C-H…π and π…π interactions.
