Supramolecular structure of bis(N,N′,N″-triisopropylguanidinium) phthalate

In the structure of the N,N′,N″-triisopropylguanidinium salt of phthalate (I), 2(IPGH)+·(C8H4O4)2−, the asymmetric unit contains two symmetry-independent cations and one anion having different inter-species hydrogen-bonding environments, which includes cyclic R22(8) and R44(16) associations. These interactions give a two dimensional layered structure.
