Manganese phthalocyanine is a magnetic transition metal complex, that exhibits organic semiconducting behavior in the bulk. Because of its high thermal and chemical stability it is a promising candidate for molecular spintronics applications. However this compound shows extraordinary electronic structure properties which can be investigated by various spectroscopic techniques as for instance EELS, PES and Ellipsometry. Here we want to present the results of our ab initio density functional calculations on this system and show how they can help to understand the significant influences on the experimentally observed electronic properties. For this purpose also environmental influences as air exposure need to be considered since they will be of decisive character in view of real applications. In particular the change of magnetic properties is crucial as this directly affects spin transport phenomena.
