通过电化学氧化二氰基酞菁钴(III)钾KCo(Pc)(CN)2得到了两种导电晶体。在乙腈中氧化得到K[Co(Pc)(CN)2]2·5CH3CN，其中酞菁环是二维堆叠的。由于一些乙腈分子很容易从晶格中除去，因此晶体在溶液外不稳定。暴露在空气中的马赛克扭曲晶体表现出相对较高的电导率（室温下约为 10 Ω−1cm−1）。另一方面，在二苯并-18-冠-6存在下，苯甲腈中的氧化生成Co(Pc)(CN)2·2H2O，其中酞菁环是三维堆叠的。该晶体中的水分子形成氢键，并且该晶体在干燥时保持稳定。该晶体的电导率在室温下约为 1 Ω−1cm−1。在这两种晶体中观察到的多维性是由酞菁的滑动堆积引起的，这是由于空间相互作用......
Two kinds of electrically conducting crystals have been obtained by the electrochemical oxidation of potassium dicyanophthalocyaninatocobalt(III), KCo(Pc)(CN)2. Oxidation in acetonitrile gives K[Co(Pc)(CN)2]2·5CH3CN, in which the phthalocyanine rings are two-dimensionally stacked. Since some of the acetonitrile molecules can be easily removed from the lattice, the crystal is not stable outside of the solution. Mosaically distorted crystals, which are exposed to air, show relatively high conductivities (≈10 Ω−1cm−1 at room temperature). On the other hand, oxidation in benzonitrile in the presence of dibenzo-18-crown-6 yields Co(Pc)(CN)2·2H2O, in which the phthalocyanine rings are three-dimensionally stacked. The water molecules in this crystal form hydrogen bonds, and the crystal is stable against drying. The conductivity of this crystal is ≈1 Ω−1cm−1 at room temperature. The multi-dimensionalities observed in these two kinds of crystals arise from a slipped stacking of phthalocyanine, due to steric intera...
