The present invention relates to an electronic device comprising a hole injection layer and/or a hole transport layer and/or a hole generating layer, wherein at least one of the hole injection layer, the hole transport layer and the hole generating layer comprises a coordination complex comprising at least one electropositive atom M having an electronegativity value according to Allen of less than 2.4 and at least one ligand L having the following structure: (I) wherein R
1
and R
2
are independently selected from the group, consisting of C
1
to C
30
hydrocarbyl groups and C
2
to C
30
heterocyclic groups, wherein R
1
and/or R
2
may optionally be substituted with at least one of CN, F, Cl, Br and I.
