The intermetallic compound CeRu4Sn6 has tentatively been classified as Kondo insulator. Its tetragonal crystal structure places it inbetween the archetypal Kondo insulators like YbB12 or Ce 3Bi4Pt3, which are cubic, and the orthorhombic "Kondo semimetals" CeNiSn and CeRhSb. It is of great interest to investigate possible anisotropies - or even nodes - of the Kondo insulating gap in CeRu4Sn6. We have succeeded, for the first time, to grow single crystals of this compound. Interestingly, we could not only reveal anisotropy between the tetragonal c direction and the tetragonal a-a plane but even within a quasi-cubic cell which happens to be formed in CeRu 4Sn6 because the length of the diagonal of the tetragonal plane c′ = √2a differs from c by only 0.2%.
