A 3D hydrodynamical model of an AGN torus (Wada, Papadopoulos & Spaans, 2009), which follows the formation of H2 out of the neutral hydrogen phase according to the evolving ambient ISM conditions (at a resolution of 0.25 pc), is used to estimate the abundance of different atomic and molecular species from a chemical model driven by X-rays. The abundance of several species is estimated based on the local hydrogen density and impinging X-ray flux at each grid element in the computational box. A 3D radiative transfer model is used to produce maps of different atomic and molecular lines to be used as diagnostic for high resolution observations of near by (< 20 Mpc) galaxy nuclei. Galactic observations of atomic and molecular gas ([C I] and mid-J CO lines) in M17 SW, obtained with CHAMP+ and FLASH on APEX, are presented as template for future extragalactic observations with ALMA.
