Single crystals of UCr{sub 2}Al{sub 20} have been grown by flux method and characterized by means of X-ray diffraction, magnetic, heat capacity and electrical transport measurements. The compound exhibits weakly temperature-dependent, moderately exchange-enhanced Pauli paramagnetism and shows regular metallic conductivity. - Graphical abstract: Pauli-like temperature dependence of the molar magnetic susceptibility of single-crystalline UCr{sub 2}Al{sub 20}. Inset: field variation of the magnetization in UCr{sub 2}Al{sub 20} taken at 1.8 K. Highlights: Black-Right-Pointing-Pointer High quality single crystals of UCr{sub 2}Al{sub 20} have been grown. Black-Right-Pointing-Pointer Crystal structure of UCr{sub 2}Al{sub 20} has been refined from the single crystal X-ray diffraction data. Black-Right-Pointing-Pointer Magnetic, heat capacity and electrical transport data have been collected for single crystalline UCr{sub 2}Al{sub 20}. Black-Right-Pointing-Pointer Previous literature report on UCr{sub 2}Al{sub 20} has been corrected and supplemented with new data.
