Ni$_{2}$Mo$_{3}$O$_{8}$ is a pyroelectric honeycomb antiferromagnetexhibiting peculiar changes of its electric polarization at magnetictransitions. Ni$_{2}$Mo$_{3}$O$_{8}$ stands out from the isostructural magneticcompounds, showing an anomalously low magnetic transition temperature andunique magnetic anisotropy. We determine the magnetic structure ofNi$_{2}$Mo$_{3}$O$_{8}$ utilizing high-resolution powder and single-crystalneutron diffraction. A noncollinear stripy antiferromagnetic order is found inthe honeycomb planes. The magnetic space group is \textit{P$_C$na}2$_1$. Thein-plane magnetic connection is of the stripy type both for the $ab$-plane andthe $c$-axis spin components. This is a simpler connection than the oneproposed previously. The ferromagnetic interlayer order of the $c$-axis spincomponents in our model is also distinct. The magnetic anisotropy ofNi$_{2}$Mo$_{3}$O$_{8}$ is characterized by orientation-dependent magneticsusceptibility measurements on a single crystal, consistent with neutrondiffraction analysis. The local magnetoelectric tensor analysis using ourmagnetic models provides new insights into its magnetoelectric coupling andpolarization. Thus, our results deliver essential information for understandingboth the unusual magnetoelectric properties of Ni$_{2}$Mo$_{3}$O$_{8}$ and theprospects for observation of exotic nonreciprocal, Hall, and magnonic effectscharacteristic to this compound family.
