A series of planar tetracoordinate carbon molecules in cyclic semisaturated hydrocarbons resulting from the combination of the C5(2-) skeleton with saturated hydrocarbon fragments is reported. The electronic stabilization and the bonding situation are studied through the analyses of molecular orbitals and the electron localization function. The magnetic properties are also revised, giving particular attention to the induced magnetic field. These systems are the first semisaturated cycles containing a planar tetracoordinate carbon stabilized only by electronic factors.
报道了一系列由C5(2-)骨架与饱和烃片段结合形成的环状半饱和烃中的平面四配位碳分子。通过分子轨道分析和电子定位函数研究了电子稳定性和键合情况。还修正了磁性，特别关注感应磁场。这些体系是首个仅通过电子因素稳定的含平面四配位碳的半饱和环。
