NaPt3B crystallizes in the hexagonal P6/mmm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 20-coordinate geometry to two equivalent Na(2), twelve equivalent Pt(1), and six equivalent B(1) atoms. In the second Na site, Na(2) is bonded in a 14-coordinate geometry to two equivalent Na(1) and twelve equivalent Pt(1) atoms. Pt(1) is bonded in a 2-coordinate geometry to two equivalent Na(1), two equivalent Na(2), and two equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Na(1) and six equivalent Pt(1) atoms.
