This letter reports about crystal structure, lattice relaxation, synthesis, and phase stability of BN-C and GaP-Si solid solution crystals. The hypothesis of atomic pair substitution is discussed and x-ray diffraction (XRD) proof is provided for the replacement of A(III)B(V) atomic pairs with C-IV pairs. Cubic BN-diamond solid solutions underwent lattice relaxation after phase transformation leading to atomic displacement disorder.
