N2  - The synthesis of an unsymmetrical squaraine dye, 2-[4-( dibutylamino )-2-hydroxyphenyl]-4-[4-( dibutylamino )phenyl] cyclobutenebis ( ylium )-1,3-diolate, has been achieved via a cross condensation reaction. In the solid state the compound is isomorphous with the known symmetrical dye bis [4-( dibutylamino )phenyl] squaraine. The single hydroxy group is found to be disordered equally over the centrosymmetrically trans-related ortho and ortho' phenyl ring sites.
