    • There is disclosed herein phosphorescent compounds, uses thereof, and devices including organic light emitting diode (OLEDs) including such compounds. Compounds of interest include: (see formula I) wherein A is Os or Ru The anionic chelating chromophores N~N, which are formed by connecting one pentagonal ring structure containing at least two nitrogen atoms to a hexagonal pyridine type of fragment via a direct carbon-carbon linkage. L is a neutral donor ligand; the typical example includes carbonyl, pyridin e, phosphine, arsine and isocyanide; two neutral L's can also combine to produc e the so-called chelating ligand such as 2,2'-bipyridine, 1,10-phenanthroline and N- heterocyclic carbene (NHC) ligand, or bidentate phosphorous ligands such as 1,2- bis(diphenylphosphino)ethane, 1,2-bis(diphenylphosphino)benzene. L can occupy either cis or trans orientation. When L occupies the trans position, the preferred structure contains both t he hexagonal fragment of N~N as well as its pentagonal fragment located at the trans position respect to their counterparts of the second N~N chromophore. When L occupies the cis position, the preferred structure consists of t he pentagonal unit of N~N chromophores residing opposite to the L. X1, X2 and X3 independently are C or N; when X2 is N, R1 is omitted, when X3 is N, R2 is omitted, R1 is H, C1-C8 alkyl, C1-C8 substituted phenyl or C1-C4 perfluoroalkyl, R2 is H, F or cyano substituent, X4 is either C or N; X4 may locate at any position of the hexagonal ring, when X4 is N and R3 a nd R4 are not linked to X4, R3 is H, methyl or C1-C3 small alkyl, R4 is H, methyl or C1-C3 small alkyl, or R3 and R4 together form an additional conjugated unit with structure
