An object is to provide a novel oxadiazole derivative represented by General Formula (G1) as a substance having a high electron-transport property. In the formula, Ar
1
represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring. When Ar
1
has a substituent, the substituent is an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 10 carbon atoms in a ring. Ar
2
represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring or a substituted or unsubstituted heteroaryl group having 4 to 9 carbon atoms. When Ar
2
has a substituent, the substituent is an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 10 carbon atoms in a ring. R
1
and R
2
independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
Two new two-dimensional (2D) coordinationpolymers, [FeII(L)2PdII(SCN)4}] (L1 = 3-(9-anthracenyl)-pyridine (1) and L2 = 4-(9-anthracenyl)-pyridine (2)), were constructed by employing square-planar [Pd(SCN)4]2− building blocks. Compound 1 exhibits a complete spin-crossover (SCO) behaviour under normal atmospheric pressure, and represents the first SCO example in a 2D system containing [Pd(SCN)4]2− units

An object is to provide a novel benzoxazole derivative. Another object is to reduce driving voltage of a light-emitting element. Still another object is to reduce power consumption of a light-emitting element, a light-emitting device, and an electronic device. A benzoxazole derivative represented by General Formula (G1) is provided. The benzoxazole derivative represented by General Formula (G1) has an electron-injecting property and an electron-transporting property; accordingly, it can be favorably used for a light-emitting element, a light-emitting device, and an electronic device.

When Ar1 has a substituent, the substituent is an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 10 carbon atoms in a ring. Ar2 represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring or a substituted or unsubstituted heteroaryl group having 4 to 9 carbon atoms. When Ar2 has a substituent, the substituent is an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 10 carbon atoms in a ring. R1 and R2 independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
