Abstract	A New family of stationary axisymmetric solutions endowed with mass, angular momentum, electric and magnetic charges, and a cosmological constant is reported. It allows for the separability of the massless Klein-Gordon and the Hamilton-Jacobi equations. This class of solutions, admitting an Abelian group of motions G2 with commuting stationary and angular Killing vectors, is of Petrov type D; the null eigenvectors of the general electromagnetic field coincide with the directions of the Debever null vectors of Weyl curvature tensor. This solution exhibits, for certain ranges of the coordinate variables, a black hole behavior; a ring singularity similar to the Kerr metric one is present. The limiting transition of this solution leads to the Carter A (1)-Plebansky (2) metric, containing the Kerr-Newman black hole solution as a subbranch, see 3, 19.
