Abstract. A formal solution of the Ornstein-Zernike equation for a multicomponent fluid consisting of hard-spherical molecules is studied with the closure of the usual hard-sphere condition and the following:

where c_ij(r) is the direct correlation function and s_ij is the closest distance between i and j species of molecules. The solution is expressed in terms of the physical solutions of a system of nonlinear algebraic equations. The result is a generalization of that of Blum (1980 J. Stat. Phys. 22 661).
