Dilithium, Li2, is a diatomic molecule comprising two lithium atoms covalently bonded together. Li2 is known in the gas phase. It has a bond order of 1, an internuclear separation of 267.3 pm and a bond energy of 101 kJ mol−1.[1]

Higher numbers of covalently bonded lithium atoms exist, albeit in small quantities. It has been observed, for example, that 1% of lithium in the vapor phase (by mass) is in the form of dilithium. Clusters of lithium atoms also exist; the most common arrangement is Li6.[citation needed]
