We present the analysis of archival X-ray data obtained with the XMM–Newton and Suzaku for a new intermediate polar identified as a counterpart of an INTEGRAL discovered γ-ray source, IGR J17195-4100. We report a new period of 1053.7±12.2s in X-rays. A new binary orbital period of 3.52\mo –\mn 0.80\mo +\mn 1.43h is strongly indicated in the power spectrum of the time series. An ephemeris of the new period proposed as the spin period of the system has also been obtained. The various peaks detected in the power spectrum suggest a probable disc-less accretion system. The soft X-rays (<3keV) dominate the variability seen in the X-ray light curves. The spin modulation shows energy dependence suggesting the possibility of a variable partial covering accretion column. The averaged spectral data obtained with XMM–Newton European Photon Imaging Camera (EPIC) cameras show a multi-temperature spectrum with a soft excess. The latter can be attributed to the varying coverage of accretion curtains.
