Syntheses and X-ray crystal structures of tetranuclear [Ag_4(#mu#_3-S_2O_3)(#mu#-S_2O_3)(#mu#-dppm)_4]{dppm = bis(diphenylphosphino)methane} and trinuclear [Ag_3(#mu#_3-Cl)(#mu#-S_2O_3)(#mu#-dppm)_3] clusters

摘要

The reaction between AgClO_4, dppm and Na_2S_2O_3·5H_2O affords the tetranuclear [Ag_4(#mu#_3-S_2O_3)(#mu#-S_2O_3)(#mu#-dppm)_4] cluster, in which the four Ag atoms from a square bridged by four dppm ligands and the two thiosulfate ligands are bound on both sides of the Ag_4 plane.
