Crystal structure of bis[(phenylmethanamine-κN)(phthalocyaninato-κ4N)zinc] phenylmethanamine trisolvate
[摘要] The asymmetric unit of the title compound, 2[Zn(C32H16N8)(C7H9N)]·3C7H9N, comprises two independent complex molecules and three benzylamine solvent molecules. Each complex molecule features a pentacoordinated Zn2+ ion within a square-pyramidal geometry, whereby the N5 donor set is defined by four atoms of the phthalocyaninate dianion (PC) and an N-bound benzylamine molecule; it is the relative orientations of the latter that differentiate between the independent complex molecules. The uncoordinated benzylamine molecules display different conformations in the structure, with syn-Car—Car—Cm—N (ar = aromatic, m = methylene) torsion angles spanning the range −28.7 (10) to 35.1 (14)°. In the crystal, N—H⋯N and N—H⋯π interactions lead to supramolecular layers in the ab plane. The layers have a zigzag topology, have the coordinating and non-coordinating benzylamine molecules directed to the inside, and present the essentially flat PC resides to the outside. This arrangement enables adjacent layers to associate via π–π interactions [inter-centroid distance between pyrrolyl and fused-benzene rings = 3.593 (2) Å] so that a three-dimensional architecture is formed.
