Synthesis, crystal structure and characterization of a new zinc phthalocyanine complex

A new complex [ZnPc(H2O)]·2DMF (1), where Pc = phthalocyanine and DMF = N,N-dimethylformamide, has been synthesized and its crystal has been determined by single-crystal X-ray diffraction method. The compound crystallizes in the triclinic space group P − 1. The lattice parameters are a = 11.668(5) Å, b = 12.186(5) Å, c = 13.939(6) Å, α = 78.697(7)°, β = 88.045 (7)°, γ = 62.949(7)°, V = 1727.4(12) Å3 and Z = 2. The Zn(II) ion is five-coordinated by four nitrogen atoms from Pc ligands and one oxygen atom from one water molecule. Notably, there are strong π–π interactions between Pc ligands, leading to 1D superamolecular structure. Moreover, the elemental analyses, FT-IR, UV–vis and Fluorescence spectra for this complex were also determined.
