The magnetism in Mn$_3$Si$_2$Te$_6$ has been investigated using thermodynamicmeasurements, first principles calculations, neutron diffraction and diffuseneutron scattering on single crystals. These data confirm thatMn$_3$Si$_2$Te$_6$ is a ferrimagnet below a Curie temperature of $T_C$approximately 78K. The magnetism is anisotropic, with magnetization and neutrondiffraction demonstrating that the moments lie within the basal plane of thetrigonal structure. The saturation magnetization of approximately 1.6$\mu_B$/Mnat 5K originates from the different multiplicities of the twoantiferromagnetically-aligned Mn sites. First principles calculations revealantiferromagnetic exchange for the three nearest Mn-Mn pairs, which leads to acompetition between the ferrimagnetic ground state and three other magneticconfigurations. The ferrimagnetic state results from the energy associated withthe third-nearest neighbor interaction, and thus long-range interactions areessential for the observed behavior. Diffuse magnetic scattering is observedaround the 002 Bragg reflection at 120K, which indicates the presence of strongspin correlations well above $T_C$. These are promoted by the competing groundstates that result in a relative suppression of $T_C$, and may be associatedwith a small ferromagnetic component that produces anisotropic magnetism below$\approx$330K.
