A series of new layered Ni_xMn_{1－xPS3 (0＜x＜1) compounds and two serier of the corresponding intercalation compounds based on the intercalation of 2,2 -bipyridine and Et4N^＋ ions into layered NixMn1－xPS3 (0＜x＜1), respectively, have been synthesized and characterized by XRD, FT-IR and elemental analysis. The magnetic measurements indicate that all layered NixMn1－xPS3 compounds exhibit antiferromagnetism with different Neel temperature, which is close related to the relative ratio of N^2＋ and Mn^2＋ ions. Compared with pristine MnPS3 or NiPS3, the mutual doping of Mn^2＋ and Ni^2＋ in layered NxMn1－xPS3 seems to weaken the magnetic interaction of the metal ion spins and result in the decrement of the antiferromagnetic phase transition temperature. As for the corresponding intercalation compounds, the magnetic dilution of the occurrence of intralayered metal ion vacancies as well as the difference of different metal ion radius and their outer shell electronic structure can obviously weaken the magnetic interaction of the spins. Therefore, all the intercalation compounds only exhibit the paramagnetism in the whole temperature range.}
