Anion-templated syntheses of octanuclear silver clusters from a silver dithiophosphate chain

Extended chain polymers [Ag(5){S(2)P(OEt)(2)}(4)(PF(6))](n), (1) could be converted to clusters of the type, [Ag(8)(X){S(2)P(OEt)(2)}(6)](PF(6)) [X = F (2); Cl (3); H (4)], by the addition of appropriate anions, of which [Ag(8)(H){S(2)P(OEt)(2)}(6)](+) showed a unique tetracapped-tetrahedral Ag8 core and contained Ag-mu-H-Ag linkages.
