摘要：

We studied the crystal structure of TiOCl up to pressures of p = 25 GPa at room temperature by x-ray powder-diffraction measurements. Two pressure-induced structural phase transitions are observed: at p(c1) approximate to 15 GPa emerges an 2a x 2b x c superstructure with b-axis unique monoclinic symmetry (space group P2(1)/m). At p(c2) approximate to 22 GPa, all lattice parameters of the monoclinic phase show a pronounced anomaly. A fraction of the sample persists in the ambient orthorhombic phase (space group Pmmn) over the whole pressure range.
