ABSTRACT: This paper is devoted to the normalized solutions of a planar

-critical Schrödinger-Poisson system with an external potential

and inhomogeneous attractive interactions
K(

)∈(

)
. Applying the constraint variational method, we prove that the normalized solutions exist if and only if the interaction strength

satisfies
