trithionic

(a) Prefixed to adjectives, or to nouns used attributively, in the names or descriptions of acids, alcohols, compound ethers or esters, oxides, salts, etc.; e.g. trisodic or trisodium, (a salt) containing 3 atoms of sodium; triethylic or triethyl (a compound) containing 3 ethyl groups; triethylene, containing three non-contiguous ethylene radicals in the molecule. So trihydric or trihydrogen, tricalcic or tricalcium, triargentic or tri-silver, tricarbon, trichloric, trimethylic or trimethyl, triplumbic, trithionic, triacetic, etc.
