A pressure cell designed for full structure determination of molecular single crystals under hydrostatic pressure ranging up to 1.5 GPa is described. We equipped a Teflon{sup TM}-sealed clamp-type pressure cell with cylindrical beryllium windows which enables us to cover wide Bragg angles over {delta}(2{theta}){approx}120 deg. The cell allows us to utilize the commercial crystallographic software package for full structure determination with use of the oscillation photographs. For low-temperature experiments, pressure is calibrated in the cell filled with Daphne 7373 oil by measuring the change in the lattice parameters of an NaCl single crystal. An example is presented for the analyses of a molecular single crystal with and without the pressure cell.
