  Neutrino-pair bremsstrahlung radiation is considered due to electron--phonon
scattering of degenerate, relativistic electrons in a lattice of spherical
atomic nuclei in a neutron star crust. The neutrino energy generation rate is
calculated taking into account exact spectrum of phonons, the Debye--Waller
factor, and the nuclear form--factor in the density range from
$10^7$~g~cm$^{-3}$ to $10^{14}$~g~cm$^{-3}$ at arbitrary nuclear composition
for body-centered-cubic and face-centered-cubic Coulomb crystals. The results
are fitted by a unified analytic expression. A comparison is given of the
neutrino bremsstrahlung energy losses in a neutron star crust composed of
ground state and accreted matter, in the solid and liquid phases.
