Complex transition metal hydrides: linear correlation of countercation electronegativity versus T–D bond lengths†
Abstract
For homoleptic 18-electron complex hydrides, an inverse linear correlation has been established between the T–deuterium bond length (T = Fe, Co, Ni) and the average electronegativity of the metal countercations. This relationship can be further employed towards aiding structural solutions and predicting physical properties of novel complex transition metal hydrides.
