Strong magnetic frustration is found in this quasi-two dimensional system, which orders antiferromagnetically (AF) at T$_{N}$=2.02 \\emph{K} from a paramagnetic liquid of Yb-dimers, having a gap $\\Delta$=4.6 \\emph{K} between the singlet ground state and the triplet excited states. Magnetic fields suppress the AF order, which vanishes at a 1.25 \\emph{T} quantum critical point.
