Doesnt LK-99 crystallize in the perovskite structure? That's very 3D. I think cuprate superconductors do too, but I'm guessing, cause it's a long time I was into that sort of thing. What do you mean by "quasi two-dimensional". Every crystal has 2d planes (apart from rare penrose-style quasicrystals) and many crystals are anisotropic. People don't call these "quasi two-dimensional" afaik.
