- wherein M in Formula 1 may be platinum (Pt).
In Formula 1, Y1 to Y4 may each independently be a chemical bond, O, S, N(Ra), C(Ra)(Rb), or Si(Ra)(Rb).
When Y1 is a chemical bond, X1 may directly bond to M, when Y2 is a chemical bond, X2 may directly bond to M, when Y3 is a chemical bond, X3 may directly bond to M, and when Y4 is a chemical bond, X4 may directly bond to M.
In an embodiment, in Formula, Y1 may be O or S, and each of Y2 to Y4 may be a chemical bond.
In an embodiment, in Formula 1, two bonds among a bond between M and either of Y1 and X1, a bond between M and either of Y2 and X2, a bond between M and either of Y3 and X3, and a bond between M and either of Y4 and X4 may each be a coordination bond, and the other two bonds may each be a covalent bond. Thus, the organometallic compound represented by Formula 1 may be electrically neutral.
In Formula 1, X1 to X4 may each independently be C or N.
For example, in Formula 1, each of X1 and X3 may be C, and each of X2 and X4 may be N.
In an embodiment, in Formula 1, Y1 may be O or S, each of Y2 to Y4 may be a chemical bond, each of X1 and X3 may be C, and each of X2 and X4 may be N.
