We report on the study of the electronic anisotropy of the (formula presented) superconductor using the in-plane resistivity measurements in the magnetic field applied perpendicular and parallel to Mg and B planes of (formula presented) single crystals. The results show the temperature dependent anisotropy of the upper critical field with the anisotropy ratio (formula presented) increasing from 2.2 close to (formula presented) up to about 3 below 30 K. Our estimation of the in-plane and out-of-plane coherence length of about (formula presented) and the electronic mean-free path (formula presented) respectively, indicates (formula presented) single crystal approaches the clean limit type-II superconductor.
