N2 - We have performed in situ synchrotron-radiation X-ray powder structural analysis in a spin-crossover complex ([Fe(ptz)6)](BF 4)2: ptz = propyltetrazole) under a photo-excitation with a continuous-wave (CW) green (532nm) laser at 91 K. The Fe2+ ions in the Fe(ptz)6 molecules take the low-spin (LS: S = 0) state at the ground state, and are photo-excited selectively into the high-spin (HS: S = 2) state. When the excitation power P exceeds the critical value, we observed a novel secondary phase which can be ascribed to the condensation of the photo-excited HS ions.
