摘要：
(Chemical Equation Presented) Grid ion: A Cu16 grid prepared with a tetratopic bishydrazone ligand has metal ions in a [4 x 4] array linked by a combination of μ-Ohydrazone and μ-NNpyridazine bridges. The six-coordinate copper ions display Jahn-Teller distortion, leading to some orbitally orthogonal bridges. Multiple intragrid magnetic-exchange pathways are present and are modeled simply by taking the molecular symmetry and the orthogonal connections into account. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
