The analysis of a simultaneous XMM-Newton/BeppoSAX plus three previous BeppoSAX observations revealed that NGC 7213 is a rather peculiar Seyfert 1. No significant Compton reflection component was observed, while an iron line complex, best explained in terms of three narrow lines, is clearly apparent in the data. Due to the absence of the reflection component, the neutral iron line is likely not produced in a Compton-thick material, but current data do not allow to choose between a Compton-thin torus and the BLR. The two ionized iron lines from $\ion{Fe}{xxv}$ and $\ion{Fe}{xxvi}$ may be produced in a photoionized gas with a column density of a few 10 23 cm -2, in analogy with the case of NGC 5506.
