Popis:	Two silica-supported Ni(I)—benzene complexes (I and II) have been prepared through acetylene cyclotrimerization. They have been characterized by electron paramagnetic resonance, infrared and diffuse reflectance spectroscopy. The following structures consistent with the spectroscopic data are proposed for these π complexes: I is a pseudotetrahedral complex where Ni(I) is bound to one benzene ligand and three surface oxygen atoms, whereas II is a distorted square planar complex where Ni(I) is bound to two benzene ligands and two surface oxygen atoms. In both complexes, benzene is acting as an η2 ligand.
