Bis(2-amino-5-benzyl-3-eth-oxy-carbonyl-4,5,6,7-tetra-hydro-thieno[3,2-c]pyridin-5-ium) bis-(4-meth-oxy-phen-yl)di-phos-phon-ate.
The asymmetric unit of the title salt, 2C17H21N2O2S(+)·C14H14O7P2 (2-), contains half of a centrosymmetric bis-(4-meth-oxy-phen-yl)di-phospho-nate anion and one 2-amino-5-benzyl-3-eth-oxy-carbonyl-4,5,6,7-tetra-hydro-thieno[3,2-c]pyri-din-5-ium cation. In the anion, the O atoms of the di-phospho-nate group are disordered over two positions with equal occupancies. In the cation, the ethyl group is disordered over two orientations with a refined occupancy ratio of 0.753 (5):0.247 (5), and the tetra-hydro-pyridinium ring adopts a distorted half-chair conformation. In the crystal, the ions are linked by C-H⋯O, N-H⋯O and C-H⋯S hydrogen bonds into a three-dimensional network.
