摘要: A remarkable autofragmentation/rearrangement sequence results in the unprecedented formation of inorganic concave cyclic anion [(NiPS4 )3 ]3- (structure shown on right) upon dissolving potassium salt charged mineral polymer 1∞ [NiPS4 ]- DMF; initial complex fluid has a transient anisotropic texture that can be identified by optical microscopy under polarized light. In contrast, [PdPS4 is stable up to 323 K as persistent, flexible, chains.
