摘要：

The molecular structure of copper phthalocyanine was determined by synchronous gas-phase electron diffraction(GED) and mass spectrometric experiment and quantum-chemical calculations. The DFT calculations with employing different basis sets give a molecular structure with D-4h symmetry that agreed satisfactorily the one found in experiment at 497 +/- A 5 A degrees C. The most important structural parameters are (GED): r(h1)(Cu-N) = 1.949(5) , r(h1)(N1-C1) = 1.381(5) , r(h1)(C1-N2) = 1.325(5) , r(h1)(C1-C2) = 1.459(5) , r(h1) (C2-C3) = 1.399(4) , r(h1)(C3-C4) = 1.397(4) , a CuN1C1 = 125.9(2)A degrees, a N1C1N2 = 128.2(5)A degrees, a C8N3C9 = 121.9(7)A degrees, a N1C1C2 = 109.5(5)A degrees, a C2C7C6 = 121.3(2)A degrees.
