I'm looking to design one of my warring planets around organolithium chemistry with seas and precipitate primarily composed of a clear organolithium solvent liquid - possibly ammonia. I've searched for physical properties of various organolithium compounds and come up against nearly all subscriber-based chemical databases.

Details of the planet:

• Gravity = Earth-ish sized ~(6.0 m/s² to 12 m/s²)

• Temperature and atmospheric pressure = Above the triple point for the clear liquid seas, and substantially above the boiling point of the air. (E.g., $30^\circ$C, 20 ATM for ammonia seas & precipitate in a 4 km deep (mostly chlorine trifluoride) troposphere). Hot (Venusian) planets are fine, better than cold ones. (As I look further this may be a bad combination)

• The sky itself is a clear vapor heavier than the precipitate vapor, some precipitate clouds can be suspended in it.

• The land mass has abundant trifluorogold and Gold pentafluoride salts (should be mostly irrelevant but it's important for their technology)

• There is no or almost no free oxygen

• People will explode or spontaneously combust on this planet, and they will explode or spontaneously combust on Earth.

I know these are interrelated, because the gas generates the pressure to make the liquid condense. So the problem first identifies an atmospheric vapor "heavy enough" to raise the pressure above the triple point for the liquid, where the liquid is an organolithium solvent; while the evaporated liquid is lighter than the air. So there's a mathematical relationship between the vapor densities.

What climate (atmosphere / sea composition) can create the temperature and pressure for a precipitating organolithium solvent?

(I don't know if ammonia is the best solvent for this, but the most important parts of the answer are

• the lithium solvency of the precipitate

• A fairly simple molecule - hopefully less than 5 bonds

• the mass of the atmosphere is sufficient to keep the solvent near the triple point. (adjust gravity and atmospheric depth to fit)

• Use approximate atmospheric gas density, other gasses mixed in or upper layers will adjust the density of the air to make precipitation.

• Ignore orbit, it will adjust to provide heat for the chemistry.

Abundant lithium, deuterium and gold helped them quickly advance in fusion reactor technology. They are completely incompatible with our climate.
