I am doing my research on Tin and Tin-Oxide and want to the know and understand atoms arrangement and their crystallographic strcucture

Dear Tanzeeha Jafari
Another paper on: Electronic structure of stannous oxide, M. Meyer a,*, G. Onida b, A. Ponchel a, L. Reining Computational Materials Science 10 (1998) 319-324, is in attachment.
Good luck
From the provided paper entitled: Electronic structure of stannous oxide, by M. Meyer a,*, G. Onida b, A. Ponchel a, L. Reining.Computational Materials Science 10 (1998) 319-324
The crystalline structures of SnO and SnO2 are tetragonal at room temperature and normal pressure (Figs. l(a) and (b)) and belong to space groups Dil, (P4/nmm) [l-3] and Dii (P42/nmm), respectively. The oxidation process results mainly in the insertion
of an oxygen plane between two tin planes in the layered SnO crystalline structure (see Figs. l(c) and (d)). As a result SnO:! is a more densely packed crystal
where each tin atom is surrounded by a slightly distorted oxygen octahedron while in SnO the tin atoms sit on the vertices of pyramids with an oxygen square
basis (Fig. l(b)). These edge sharing pyramids form the layers of the SnO structure with tin vertices lying alternately above and below them. The layers are stacked perpendicularly to the c crystallographic axis with tin atoms facing each other (Fig. l(d)). In order to well understand the stability of this structure and the cohesion between its layers, it is important to have an accurate description of the atomic and electronic structure of SnO and of the relation between electronic and geometric configurations.2.
