We have studied self-assembled monolayers of organic dinickel (II) complexes with an S=2 high paramagnetic state, anchored to a Au(111) surface via thiol groups using STM at room temperature. Our data clearly reveal the dense distribution of 2-4 nm sized objects on the Au surface, which evidences the growth of a closed molecular monolayer. The monolayers, however, do not show long-range order of the individual molecules.
