  Coulomb plasmas crystallize in a number of physical systems, such as dusty
plasmas, neutron star crusts, and white dwarf cores. The crystal structure of
the one component and binary plasma has received significant attention in the
literature, though the less studied multicomponent plasma may be most relevant
for many physical systems which contain a large range of particle charges. We
report on molecular dynamics simulations of multicomponent plasmas near the
melting temperature with mixtures taken to be realistic X-ray burst ash
compositions. We quantify the structure of the crystal with the bond order
parameters and radial distribution function. Consistent with past work, low
charge particles form interstitial defects and we argue that they are in a
quasi-liquid state within the lattice. The lattice shows screening effects
which preserves long range order despite the large variance in particle charges
which may impact transport properties relevant to astrophysics.
