As we know, differences in coordination environment of transition metal atoms may lead to distinct types of orbital splitting, and thus distinct electronic distributions on molecular orbitals.

(e.g. octahedral and square pyramidal)

This ligand field theory (LFT) is usually used in a context that a transition metal ion is complexed with ligands like CO, CN, NH3, H2O, etc.

What I want to know is: does LFT still work for MOx polyhedra in an inorganic solid material? In which besides MOx polyhedra there are other polyhedra or ions constituting the compound.

Like in Li2VSiO5, V atoms lie in VO5 square pyramids, Si atoms lie in SiO4 tetrahedra (connected to VO5 by corner sharing). Would the electronic distribution of such compound be different from a compound in which V atoms lie at octahedra centres?

Thanks a lot!
