We have discovered four new approximant phases of the B-Mg-Ru decagonal quasicrystal. Six phases were observed in electron diffraction patterns of B-Mg-Ru alloys prepared at 1673 K from B2xMg(1-x)Ru2(1-x) (x = 0.44-0.48). Two of them are known, B4Mg2Ru5 and B11Mg5Ru13, and the other four are new approximant phases. Their lattice parameters range from a = 0.84 nm to 8.5 nm; some of them can be described with the Fibonacci sequence. We suggest tiling models of these approximants using two subunits of B4Mg2Ru5 and B11Mg5Ru13, 'hexagon' and 'boat'.
