报道了配体 (N, O, F) 2 与金属 (Mn) 1 的“原子间”或“交叉”X 射线跃迁的研究。我们发现K beta”特征的能量与配体2s结合能相关，可用于识别配体的类型。对于氧连接的Mn化合物，K beta”跃迁的强度随着Mn-O距离的增加呈指数下降。这可用于预测类似于 0.1 埃的距离。 K beta(2,5) 能量显示出类似于每单位氧化态 1 eV 的变化。 K beta ”和 K beta(2,5) 过渡是过渡金属配合物结构表征的有前景的工具。(C) 1999 Elsevier Science B.V. 保留所有权利。
A study of ligand (N, O, F) 2s to metal (Mn) 1s 'interatomic' or 'crossover' X-ray transitions is reported. We show that the energy of the K beta " feature is related to the ligand 2s binding energy and can be used to identify the type of ligand. For oxygen-ligated Mn compounds, the strength of the K beta " transition decreases exponentially with increasing Mn-O distance. This can be used to predict distances to similar to 0.1 Angstrom. The K beta(2,5) energy shows shifts of similar to 1 eV per unit oxidation state. K beta " and K beta(2,5) transitions are a promising tool for structural characterization of transition-metal complexes. (C) 1999 Elsevier Science B.V. All rights reserved.
