- R11 and R12 each represents an aryl group or an atomic group necessary for forming a heterocycle upon connection between R11 and R12;
- X13 represents an oxygen atom, a sulfur atom, —C(R13)R14—, or —NR15—;
- R13, R14, and R15 each represents a hydrogen atom or a substituent;
- Z1 represents an atomic group necessary for forming a 5-membered or 6-membered ring;
- M1 represents a metal ion;
- n1 represents an integer of 1 or more;
- L1 represents a ligand;
- and m1 represents an integer of 0 or more.
