6 6 Figure S3. The bifurcated hydrogen bonding of the tetrazole group in the structure of [MoO 3 (trtz)] (7), viewed along the direction of Mo-oxide helices. Symmetry codes: c) -0.5-x, 0.5-y, 0.5-z; d) -0.5+x, y, 0.5-z. When neglecting N7-H---O2d branch of this bifurcated bond, the hydrogen bonded dimer tetrazole/tetrazole provides simple connection of the ligands into extended linker between MoO 3 helices. This convenient scheme was used for the discussion of the resulting 3D structure, as five-fold interpenetrated asf framework. However, taking into account the additional NH--- O interactions (which completely cross all the interpenetrated nets), the interpenetration disappears and a single 3D framework of complex topology is found.
