Bis(2-methylanilinium) diaquabis[dihydrogendiphosphato(2-)]cobaltate(II)

A. Selmi, S. Akriche and M. Rzaigui

Abstract: In the title cobalt(II) complex with 2-methylanilinium and diphosphate, (C₇H₁₀N)₂[Co(H₂P₂O₇)₂(H₂O)₂], a three-dimensional network is built up from anionic layers of [Co(H₂P₂O₇)₂(H₂O)₂]^2- units and 2-methylanilinium cations located between these layers. The dihydrogendiphosphate groups present a bent eclipsed conformation, while the Co²⁺ ions lie on inversion centers. An intricate network of O-HO and N-HO hydrogen bonds is established between the different components, assuring the cohesion of the network with other interactions, being of electrostatic and van der Waals nature.
