The behavior in magnetic field of a paramagnetic center is characterized byits $g$ tensor. An anisotropic form of the latter implies different kind ofresponse along different crystallographic directions. Here we shed light on theanisotropy of the $g$ tensor of Yb$^{3+}$ 4$f^{13}$ ions in NaYbS$_2$ andNaYbO$_2$, layered triangular-lattice materials suggested to host spin-liquidground states. Using quantum chemical calculations we show that, even if theligand-cage trigonal distortions are significant in these compounds, thecrucial role in realizing strongly anisotropic, `noncubic' $g$ factors isplayed by inter-layer cation charge imbalance effects. The latter refer to theasymmetry experienced by a given Yb center due to having higher ionic chargesat adjacent metal sites within the magnetic $ab$ layer, i.e., 3+ nearestneighbors within the ab plane versus 1+ species between the magnetic layers.According to our results, this should be a rather general feature of 4$f^{13}$layered compounds: less inter-layer positive charge is associated with strongerin-plane magnetic response.
