organic compounds
Interaction of piperazine with 4,4′-sulfonyldiphenol at ambient temperature in methanol yields the salt, piperazin-1,4-diium di(4,4′-sulfonyldiphenolate), (C4H12N2)2+.2(C12H9O4S)− in which pairs of phenolate anions form cyclic dimers; the cations act as multiple hydrogen-bond donors, of both N-HO and C-HO types, which tie these dimers into stacks enclosing channels 4.3 Å in diameter.
