A compound comprising a metal M and a first ligand LA having a structure of Formula I, is described. In Formula I, each independently represents a single bond or a double bond; each of X1′ to X4′ is independently C, N, or NR′; at least one of X1 to X4 is NR′; each RA′, R′, R1, R2, and R3 is independently hydrogen or a general substituent; at least one of RA′, R′, R1, R2, and R3 comprises the metal M; when X1 and X2 are both NR′, the B atom of Formula I forms a maximum of one direct bond to a nitrogen atom, and does not form a direct bond to an oxygen atom; and any two adjacent RA, R′, R1, R2, and R3 can be joined or fused to form a ring. Formulations, OLEDs, and consumer products including the compounds are also described.
