Homogeneous structures A(x)B(y) with identical A-A or B-B self-coordination numbers T-1, T-2, T-3, of nearest, next-nearest and third neighbors; are selected. The maximum T-1 values are 2 2 2 (1D row), 6 6 6 (2D hexagonal net) and 12 6 24 (3D cubic close-packing). Reduced T-1 or T-2 values for A(x)B(y) can be related with attractive or repulsive A-A (or B-B) interactions. A single set of T-1 T-2 T-3; y/x values 1 was obtained for y/x = 1 - 4 and 6. The y/x = 2 structures of three equivalent positions A, B and C are unfavourable for A = circle plus and B = circle minus charge or direction of magnetic moments. The spatial distribution of positive and negative potential near A(+) and B- positions gives rise to neutral C positions. Frustrated magnetic moments at C positions are disordered.
