We have synthesized a new intermetallic compound YbNi2Si3 which crystallizes in the space group Immm with the metric a = 3.860Å, b = 3.862Å, and c = 24.068Å. Single crystals have been grown from Sn flux in a closed SiO2 glass ampoule. Clean free-standing crystals could be obtained after dissolving the solid flux with liquid gallium and cleaning with a solution of iodine in dimethyl formamide. The magnetic dc susceptibility was measured parallel and perpendicular to the c axis. We find a rather strong anisotropy of the Curie-Weiss-like susceptibility down to 2.3 K. Measurements of the specific heat will be reported as well.
