La estructura del tris(tetrabutilamonio) hidrógeno pirofosfato (HPP) ha sido estudiada en disolución y en estado sólido por RMN de 31P. Cálculos GIAO/DFT de la molécula aislada en sus conformaciones abierta y cerrada, de sus complejos con una molécula de agua y de los efectos de disolvente con un modelo del continuo han servido para discutir los datos experimentales de RMN. Contrariamente a los datos de la literatura, HPP da una señal única en disolución que se ensancha considerablemente al enfriar hasta 193 K sin alcanzar la coalescencia. En estado sólido se observan dos señales muy próximas que los cálculos no logran reproducir
