      abstract     = {On the basis of single-crystal x-ray diffraction we show
                      that TiPO4 undergoes a spin-Peierls distortion below 74.5(5)
                      K, with a dimerization of the Ti chains along the c axis.
                      Between 74.5(5) and 111.6(3) K, TiPO4 develops an
                      incommensurate (IC) phase with temperature-dependent q
                      vector (σ1,0,0). Density functional calculations strongly
                      suggest that the IC phase results from a frustration of the
                      lock-in spin-Peierls transition due to the competition of
                      three energetically almost degenerate crystal structures and
                      elastic coupling of the Ti chains via the bridging PO4
                      units. The phase transition into the IC phase is of second
                      order, but the lock-in transition into the spin-Peierls
                      distortion below 74.5 K is of weak first order in nature.},
