A discrete centrosymmetric (H2O)(20)(CH3OH)(4) binary cluster was confined in the cavity of a metal-ligand hybrid [Ag-4(bpda)(2)(bpp)(4)center dot 14H(2)O center dot 2CH(3)OH] (n) (1) (where bpp = 1,3-bis(4-pyridyl)propane and H2bpda = 2,2';-biphenyldicarboxylic acid). The novel mixed water-methanol cluster consists of one grail-shaped hexadecameric cluster, four dangling water and four hanging methanol molecules. The (H2O)(16) cluster is composed of two pairs of edge-sharing (H2O)(5) rings attached to one (H2O)(4) core with twenty hydrogen bonds. Alternatively, the (H2O)(16) cluster is structurally similar to a complicated hydrocarbon generated by undergoing [2+2] cycloaddition of 1,2,3,4,5,6-hexahydropentalene, which reveals the resemblance between water clusters and organic compounds.
