  Neutron diffraction and magnetic susceptibility studies of a polycrystalline
SrCr$_2$As$_2$ sample reveal that this compound is an itinerant G-type
antiferromagnet below the N${\rm \acute{e}}$el temperature $T_{\textrm N}$ =
590(5) K with the Cr magnetic moments aligned along the tetragonal $c$ axis.
The system remains tetragonal to the lowest measured temperature ($\sim$12 K).
The lattice parameter ratio $c/a$ and the magnetic moment saturate at about the
same temperature below $\sim$ 200 K, indicating a possible magnetoelastic
coupling. The ordered moment, $\mu=1.9(1)~\mu_{\rm B}$/Cr, measured at $T = 12$
K, is significantly reduced compared to its localized value ($4~\mu_{\rm
B}$/Cr) due to the itinerant character brought about by the hybridization
between the Cr $3d$ and As $4p$ orbitals.
