Cobalt(III)H2O(NH3)3 pyrophosphate has been shown by proton and 31P nuclear magnetic resonance (NMR) to be a facial bidentate complex. Cobalt(III)H2O(NH3)3 adenosine diphosphate has been resolved into lambda and delta isomers by chromatography on cycloheptaamylose. Both the lambda and delta forms are a pair of isomers that are not separated by cycloheptaamylose, reverse phase high-pressure liquid chromatography (HPLC), or cation exchange chromatography. These isomers presumably represent syn- and anti-arrangement of coordinated water and adenosine.
通过质子和³¹P核磁共振(NMR)已表明,焦磷酸钴(III)H₂O(NH₃)₃是一种面式双齿配合物。钴(III)H₂O(NH₃)₃二磷酸腺苷已通过在环糊精上的色谱法拆分为λ和δ异构体。λ和δ形式均为一对异构体,它们不能通过环糊精、反相高压液相色谱(HPLC)或阳离子交换色谱法分离。这些异构体可能代表配位水和腺苷的顺式和反式排列。
