<jats:title>Abstract</jats:title>
<jats:p> Neutron scattering results on Se<jats:sub>1-x</jats:sub>Te<jats:sub>x</jats:sub> melts (x = 0.3, 0.6, 0.8) obtained at 460 °C are combined with earlier X-ray diffraction data. The behaviour of the number and distance of nearest neighbours is discussed with respect to chemical short-range order and transition from twofold to three-fold coordination. For Se<jats:sub>70</jats:sub>Te<jats:sub>30</jats:sub> the radial concentration correlation function 4πr<jats:sup>2</jats:sup> ρcc(r) has been evaluated. It shows clearly the preferred formation of unlike pairs (Se-Te) within the chains.</jats:p>
