The crystal structure of TiB

Abstract

The structure of titanium monoboride has been determined by single-crystal and powder methods to be of the FeB-type. The dimensions of the orthorhombic unit cell are ao = 6.12, b0 ----3.06 and co -~ 4.56/~. As in other borides of composition MB, the boron atoms form zigzag chains through the lattice. Short interatomic distances indicate a higher-than-normal valence for the titanium atoms, when calculated by application of the Pauling equation, D(n) ----D(1)--0.6 log n.
