In this work we analyze the quantum correlations in a spin-1/2 Ising-XXZdiamond chain with one plaquette distorted impurity. We have shown that theintroduction of impurity into the chain can significantly increase entanglementas well as quantum correlations compared to the original model, withoutimpurity. Due to the great flexibility in the choice of impurity parameters,the model presented is very general and this fact can be very useful for futureexperimental measurements. In addition to entanglement and quantum coherence,we studied quantum teleportation through a quantum channel composed by acoupled of Heisenberg dimers with distorted impurity in an Ising-XXZ diamondchain, as well as fidelity in teleportation. Our analysis shows that theappropriate choice of parameters can greatly increase all the measuresanalyzed. For comparison purposes, we present all our results together with theresults of the measurements made for the original model, without impurity,studied in previous works.
