A theoretical model to explain the phenomenon of spin crossover in the [MnL2]NO3 compound is elaborated. The model takes into account the low symmetry crystal field acting on the manganese ion and the cooperative long-range electron-deformational interaction facilitating the spin transition. The range of the crystal field parameters for which the low-lying part of the energy spectrum ... https://shopredoners.shop/product-category/the-easy-rider-short/
