Based on a simple model for ordering of hexagons on square planar lattice, anattempt has been made to consider possible structure of C(_{60}) fullerite inits low temperature phase. It is shown that hexagons, imitating fullerensoriented along (C_{3}) axes of \emph{sc} lattice, can be ordered into an idealstructure with four non-equivalent molecules in unit cell. Then the energydegeneracy for each hexagon rotations by (\pi /3) around its (C_{3}) axisleaves the translational and orientational order in this structure, but leadsto a random distribution of (\pi /3) rotations and hence to {}``averaged{}''unit cell with two molecules. However the most relevant structural defects arenot these intrinsic \char`\"{}misorientations\char`\"{} but certain wallsbetween the domains with different sequencies of the above-mentioned two(non-ideal) sublattices. Numeric estimates have been made for the anisotropicinter-molecular potential showing that the anisotropy is noticeably smaller formolecules in walls than in domains
