Based on the reaction of bis(η5-methylcyclopentadienyl) dichlorotitanium ( , Cp′ = η5-C5H4Me) with 3-hydroxy-2-naphthoic acid (HNA-1) and 1-hydroxy-2-naphthoic acid (HNA-2), in the presence of β-cyclodextrin polymer (βCDP) as a catalyst, two titanocene complexes: bis(η5-methylcyclopentadienyl) 3-hydroxy-2-naphthoatotitanium (1) and bis(η5-methylcyclopentadienyl)1-hydroxy-2-naphthoatotitanium (2), were synthesized and characterized by elemental analysis, IR and 1H NMR spectra. X-ray diffraction analysis of 1 and 2 show mononuclear TiIV and indicate that the geometries at titanium are distorted tetrahedra with coordination number four. Both complexes exhibit 3-D frameworks constructed through H-bonding and C–H ··· π interactions. There are no π–π stacking interactions between the naphthyl rings and cyclopentadienyl rings of 1, while there are three types of π–π interactions in the structure of 2, owing to their different hydroxyl position in naphthalene rings.
