Abstract

The crystal structure of rubidium hydrogen fumarate has been determined using x-ray diffraction data for the three principal projections. The structure has been refined by the method of least squares with R values of 0.112 (hk0), 0.111 (0kl) and 0.110 (h0l). The fumarate group is found to be non-planar with one of the COOH groups twisted by about 35° from the plane of the rest of the atoms. Hydrogen bonds of 2.58 Å link the molecules to form extensive chains along the [010] axis. Rb+–O distances range from 2.80 Å to 3.19 Å with five-fold coordination.
