Extreme synthetic conditions create material with a seemingly implausible electron count

Chemists in Germany have isolated a silver-rich oxide with an electron count in conflict with its physical properties. The team has rationalised its observations by attributing them to an unusual bonding scenario featuring an extra stabilising interaction between silver atoms.
