A molecule with two pendant phenylarsine moieties according to the general structural Formula (I) and tautomers, acids, and salts thereof, wherein: (i) Rl or R2, are each independently O-, S-, OR 3 or SR 3 with the provision that if either Rl or R2 is absent, the other remaining group is =0 or =S; or Rl and R2, together with the arsenic atom, form a ring according to one of the general structural Formulae (II), (III), (IV), or (V), wherein R3 is H, CH(OH)CH20H, or (CH2)y- Y, with q being 1-4 and Y being H, OH, NH2, SH, COOH, OAc, CONH2 or CN, and Z represents a hydrocarbon chain comprising 2-4 singly or doubly bonded carbon atoms each of which may be further substituted with one or more of hydrogen, methyl, ethyl, 1-propyl, 2-propyl, methoxy, hydroxy, amino, carboxy, sulfo, oxo, thio, halo (fluoro, chloro, bromo, or fluoro) and (CH2)" "SO3, wherein n" is 1 or 2.
