N2 - We use a recently proposed perturbative numerical renormalization group algorithm to investigate ground-state properties of a frustrated three-dimensional Heisenberg model on an anisotropic lattice. We analyze the ground-state energy, the finite size spin gap and the static magnetic structure factor. We find in two dimensions a frustration-induced gapless spin liquid state which separates two magnetically ordered phases. In the spin liquid state, the magnetic structure factor shows evidence that this state is made of nearly disconnected chains reminiscent of a sliding Luttinger liquid. This spin liquid state is unstable against unfrustrated interplane couplings.
