摘要：

Interionic C-H ... O hydrogen bond distances have been investigated in organometallic and inorganic salts showing that the average lengths unequivocally follow the order [(M)C-H](+)...[O](-) < (M)C-H ... O (M = first row transition metal) and [(PPh4)C-H](+)...[O-M](-) < [(PPN)C-H](+)...[O-M](-) < [(BPh4)C-H](-)... [O-M](+), which is the order of decreasing charge assistance to the weak hydrogen bonds.
