Crystal structure of bis­[(phenyl­methanamine-κN)(phthalocyaninato-κ(4) N)zinc] phenyl­methan­amine tris­olvate

The asymmetric unit of the title compound, 2[Zn(C(32)H(16)N(8))(C(7)H(9)N)]·3C(7)H(9)N, comprises two independent complex mol­ecules and three benzyl­amine solvent mol­ecules. Each complex mol­ecule features a penta­coordinated Zn(2+) ion within a square-pyramidal geometry, whereby the N(5) 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-C(ar)—C(ar)—C(m)—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.
