1. An organometallic compound represented by Formula 1: wherein, in Formula 1, M is selected from a first-row transition metal, a second-row transition metal, and a third-row transition metal; A11 is selected from a C3-C20 heteropolycyclic group comprising a nitrogen atom (N) as a ring-forming atom; X11 is a nitrogen atom (N) or CR11; X12 is N or CR12; X13 is N or CR13; X14 is N or CR14; X15 is N or CR15; X16 is N or CR16; X17 is N or CR17; R11 to R18 are each independently selected from a hydrogen, deuterium, —F, —Cl, —Br, —I, a hydroxyl group, a cyano group, a nitro group, an amino group, an amidino group, a hydrazine group, a hydrazone group, a carboxylic acid group or a salt thereof, a sulfonic acid group or a salt thereof, a phosphoric acid group or a salt thereof, a substituted or unsubstituted C1-C60 alkyl group, a substituted or unsubstituted C2-C60 alkenyl group, a substituted or unsubstituted C2-C60 alkynyl group, a substituted or unsubstituted C1-C60 alkoxy group, a substituted or unsubstituted C3-C10 cycloalkyl group, a substituted or unsubstituted C1-C10 heterocycloalkyl group, a substituted or unsubstituted C3-C10 cycloalkenyl group, a substituted or unsubstituted C1-C10 heterocycloalkenyl group, a substituted or unsubstituted C6-C60 aryl group, a substituted or unsubstituted C6-C60 aryloxy group, a substituted or unsubstituted C6-C60 arylthio group, a substituted or unsubstituted C1-C60 heteroaryl group, a substituted or unsubstituted monovalent non-aromatic condensed polycyclic group, a substituted or unsubstituted monovalent non-aromatic condensed heteropolycyclic group, —C(═O)(Q1), —N(Q1)(Q2), and —Si(Q1)(Q2)(Q3), wherein at least two adjacent groups of R11 to R17 are optionally linked to each other to form a saturated or unsaturated ring; Q1 to Q3 are each independently selected from a hydrogen, deuterium, a substituted or unsubstituted C1-C10 alkyl group, and a substituted or unsubstituted C6-C60 aryl group; b18 is selected from 1, 2, 3, 4, 5, 6, 7, and 8; n is 1, 2, 3, and 4; L11 is selected from a monodentate ligand and a bidentate ligand; and m is selected from 0, 1, 2, 3, 4, 5, and 6. |
