Complex transition metal hydrides: Linear correlation of countercation electronegativity versus T-D bond lengths

© 2015 The Royal Society of Chemistry. 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
