摘要：
A generalized model of angular overlapping was used to analyze the magnetic properties of polynuclear complexes. The structural elements of these complexes contain planar binuclear fragments of the M(LR)2M type. The maximum ferromagnetism for the monoatomic bridges corresponds to θ = ∠MLM, which is about 100°. Weak planar σ interactions between L and R displace the ferromagnetism maximum towards lower θ, while π interactions shift it towards higher θ. In almost all cases, strong planar interactions (∠LLR ∼ 180°) are responsible for strong antiferromagnetism.
