A new chromium(III) complex with dipicolinate anion i.e. [Cr(dipic)(H2O)3]Cl ⋅ 2 H2O and its crystal structure, the physicochemical properties and catalytic activity for the oligomerization reaction of 2-chloro-2-propen-1-ol is presented in this report. The X-ray analysis of the new chromium(III) complex has been performed and based on the X-Ray analysis the crystallographic parameters have been determined. Conductivity titrations have been performed to determine the stoichiometry of the complex in aqueous solutions. The stability of the titled compound in aqueous solutions has been examined by potentiometric titrations. The nitro blue tetrazolium test has been carried out to check the antioxidant properties of [Cr(dipic)(H2O)3]Cl ⋅ 2 H2O. The oligomerization reaction of 2-chloro-2-propen-1-ol alcohol catalyzed by the titled chromium(III) complex has been conducted. The catalytic activity of [Cr(dipic)(H2O)3]Cl ⋅ 2 H2O has been calculated. The oligomerization products have been characterized using the nuclear magnetic resonance spectroscopy, the matrix-assisted laser desorption/ionization–time-of-flight mass spectrometry and the infrared spectroscopy.
