Crystal structures and hydrogen bonding in the isotypic series of hydrated alkali metal (K, Rb and Cs) complexes with 4-amino-phenyl-arsonic acid.

ABSTRACT: The structures of the alkali metal (K, Rb and Cs) complex salts with 4-amino-phenyl-arsonic acid (p-arsanilic acid) manifest an isotypic series with the general formula [M₂(C₆H₇AsNO₃)₂(H₂O)₃], with M = K {poly[di-μ₃-4-amino-phenyl-arsonato-tri-μ₂-aqua-dipotassium], [K₂(C₆H₇AsNO₃)₂(H₂O)₃], (I)}, Rb {poly[di-μ₃-4-amino-phenyl-arsonato-tri-μ₂-aqua-dirubidium], [Rb₂(C₆H₇AsNO₃)₂(H₂O)₃], (II)}, and Cs {poly[di-μ₃-4-amino-phenyl-arsonato-tri-μ₂-aqua-dirubidium], [Cs₂(C
