2O}2(PPh3)2]BF4 (2A′). DFT calculations (B3LYP with the D95V(d,p) basis set for C, N, H and O and LanL2DZ with Los Alamos ECPs for Ru, P and Cl) revealed that the binding of aminomethylphosphanes to the ruthenium centre leads to the P C bonds elongation, which may finally result in breaking one of them and phosphane’s reduction from tertiary to secondary ones.
