磷酸二甲酯与Co（III）络合物在水中结合的平衡常数从6.2 M-1增加到210 M-1，在结合的磷酸盐和金属络合物之间加入单个氢键。晶体结构显示氢键距离为1.96 π。金属配位和氢键之间的协同效应也可以观察到氟离子结合，但不是溴离子结合。
The equilibrium constant for binding of dimethyl phosphate to a Co(III) complex in water increases from 6.2 to 210 M-1upon addition of a single hydrogen bond between the bound phosphate and the metal complex. Crystal structure reveals that the hydrogen bond distance is 1.96 Å. The synergistic effect between metal coordination and hydrogen bonding can also be observed for fluoride binding but not for bromide binding.
