Notes: (a) the H-atom epsilons are restrained to the values from DFT calculations. (b) The diagonal elements of epsilon for non-H atoms from DFT calculations are 13, 19, 13 × 10−1 Å2. (c) Goodness-of-fit (GOF) based on numbers of observations (Obs), restraints (Restr) and parameters (Param). (d) wR 2 = [Σw(U obsU calc)2wU obs 2]1/2.
