Extended-data synthesis details show that a zinc interlayer was used to promote larger Na4B60 single crystals. Degassing at 900 °C and 10−4 Pa for 48 hours was compared with lower-temperature or argon-flow conditions, which retained more residual sodium.",

  "searched": "Read the primary Nature Chemistry report and its extended-data synthesis details. Checked precursor composition, high-pressure route, crystal-growth configuration, degassing temperature/pressure/duration, and residual-sodium controls. The route is a two-step precursor strategy: high-pressure Na4B60 crystal formation is aided by a zinc interlayer, followed by vacuum sodium removal; degassing temperature and atmosphere affect residual sodium, so the synthesis statement should not be read as an unspecified one-step or condition-independent process."
