  We report optimized crystal growth conditions for the quarternary compound
AgCrP$_2$S$_6$ by chemical vapor transport. Compositional and structural
characterization of the obtained crystals were carried out by means of
energy-dispersive X-ray spectroscopy and powder X-ray diffraction.
AgCrP$_2$S$_6$ is structurally closely related to the $M_2$P$_2$S$_6$ family,
which contains several compounds that are under investigation as 2D magnets.
As-grown crystals exhibit a plate-like, layered morphology as well as a
hexagonal habitus. AgCrP$_2$S$_6$ crystallizes in monoclinic symmetry in the
space group $P2/a$ (No. 13). The successful growth of large high-quality single
crystals paves the way for further investigations of low dimensional magnetism
and its anisotropies in the future and may further allow for the manufacturing
of few-layer (or even monolayer) samples by exfoliation.
