We report on the synthesis of Tin+1SnCn (MAX phases) by hot isostatic pressing starting with titanium, tin, and carbon powders. In addition to the already known Ti2SnC compound (211 MAX phase), a new 312 MAX phase, Ti3SnC2, is formed. Its lattice parameters, deduced from Rietveld analysis of X-ray diffraction patterns, are found to be a = 0.31366 nm and c = 1.8650 nm.
