The intercalation of magnetic elements in nonmagnetic van der Waals (vdW) materials is an effective way to design different (quasi) 2D magnets and produce exotic properties. More specifically, how exactly the intercalator distributed within synthetic crystal can also affect physical properties substantially. In contrast conventional $3d$ transition-metal intercalates niobium tantalum dichalcogenides, which commonly have $2\ifmmode\times\else\texttimes\fi{}2$ or $\sqrt{3}\ifmmode\times\else\texttimes\fi{}\sqrt{3}$ type ordered intercalation, we report a disordered Co atoms between vdW gaps $2H$-tantalum disulfide ($2H\text{-Ta}{\mathrm{S}}_{2}$). obtained quasi-vdW ferromagnet ${\mathrm{Co}}_{0.27}\mathrm{Ta}{\mathrm{S}}_{2}$ shows both perpendicular anisotropy thickness-tunable interestingly, temperature dependence electrical resistivity semiconductorlike behavior, metallic feature other analogs this material family. This unexpected phenomenon be understood through variable-range hopping mechanism, due highly intercalation. Moreover, side-jump scattering dominated anomalous Hall effect, related distribution intercalators.
