OG exemplary drawing
 
1. A metal coordination complex comprising a structure of the following Formula I

OG Complex Work Unit Chemistry
wherein:
Q is C or Si;
m and n are each independently 1 or 2;
custom character represents a single bond or a double bond in a Lewis structural drawing;
each one of ring A and ring B independently comprises exactly one double bond in at least one Lewis structural drawing;
RA and RB each independently represent di to the maximum allowable substitution;
each RA and RB is independently a hydrogen, or a substituent selected from the group consisting of deuterium, halogen, alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, germyl, boryl, selenyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carboxylic acid, ether, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof;
at least one pair of adjacent substituents RA are joined to form a 5- or 6-membered aromatic or heteroaromatic ring, referred to as ring A1′;
wherein, if ring A1′ is a benzene ring and two substituents RA are joined to form a second benzene ring fused to ring A, then ring A1′ and the second benzene ring are fused together;
at least one pair of adjacent substituents RB are joined to form a 5- or 6-membered aromatic or heteroaromatic ring, referred to as ring B1′;
wherein, if ring B1′ is a benzene ring and two substituents RB are joined to form a second benzene ring fused to ring B, then ring B1′ and the second benzene ring are fused together;
wherein (i) at least one of RA or RB comprises a ring system, which can be aromatic or heteroaromatic, with 3 to 30 ring atoms, wherein one ring of the ring system is bonded to metal, (ii) ring A1′ or ring B1′ is bonded to a metal M, or (iii) both condition (i) and condition (ii); and
the metal M is selected from the group consisting of Os, Ir, Pd, Pt, Cu, Ag, and Au.
