摘要双氰基酞菁钴（III）阴离子[Co（Pc）（CN）2]-的电结晶得到了三种不同维度的中性自由基晶体。在含溴仿的晶体Co（Pc）（CN）2·2CHBr 3中形成Co（Pc）（CN）2的一维阵列。在Co（Pc）（CN）2.2CHCl3晶体中形成了二维的Co（Pc）（CN）2片层。在Co（Pc）（CN）2·2 H2O中形成了Co（Pc）（CN）2的三维网络。电导率各向异性与π-π相互作用的维数很好地一致。的电导率值，这是相当高的中性自由基固体，是系统地增加与增加的维数，这表明在中性自由基系统的导电限制因素，现场库仑排斥能，可以通过增加维数减少。
Abstract Electrocrystallization of the dicyanophthalocyaninatocobalt(III) anion, [Co(Pc)(CN)2]−, gives three kinds of neutral radical crystals which are different in dimensionality. One-dimensional arrays of Co(Pc)(CN)2 are formed in the bromoform containing crystal, Co(Pc)(CN)2.2CHBr3. Two-dimensional sheets of Co(Pc)(CN)2 are formed in a crystal of Co(Pc)(CN)2.2CHCl3. A three-dimensional network of Co(Pc)(CN)2 is formed in Co(Pc)(CN)2.2H2O. The conductivity anisotropy is in good agreement with the dimensionality of the π-π interaction. The conductivity value, which is rather high as neutral radical solids, is systematically increased with increasing the dimensionality, suggesting that the conduction-limiting factor in a neutral radical system, on-site Coulomb repulsion energy, can be reduced by increasing the dimensionality.
