Bis(benzylammonium)bis(oxalato)cuprate(II) is a layered organic bulk crystal. Previous work on this crystal compound indicated that the crystal exhibits a friction anisotropy depending on the molecular structure. To further study the dependence of surface features and molecular composition the crystal was probed by non contact scanning probe microscopy in ultra high vacuum at room temperature. By means of molecular tracking, multiple series of 2D force maps were performed along the [100] crystal axis. The background of a second minimum in the extracted interaction force curves, revealed by our measurements, will be analyzed and discussed.
