ABSTRACT
The title compound, [Zn(C(32)H(16)N(8))(C(5)H(6)N(2))].2C(4)H(8)O, consists of one (phthalocyaninato)zinc (ZnPc) unit, a coordinated 4-aminopyridine (4-ap) molecule and two tetrahydrofuran (THF) solvent molecules. The central Zn atom is (4+1)-coordinated by four isoindole N atoms of the Pc core and by the pyridine N atom of 4-aminopyridine. The Zn atom is displaced by 0.4464 (8) A from the isoindole N(4) plane towards the pyridine N atom. The crystal structure is stabilized by intermolecular amine-phthalocyaninate N-H...N hydrogen bonds and pi-pi interactions between the aggregated Pc rings, which form molecular layers, and by weak van der Waals interactions between the layers. As well as hindering the aggregation of ZnPc molecules by occupying an axial position, the amino group will add new interactions which will favor applications of ZnPc, for example, as a sensitizer of photodynamic therapy.
