thin films using a spin‐coating method are reported. Compounds

2
and

differ either by tin oxidation state or by Sn:S ratio (Sn:S = 2:1 in

, 1:1 in

and 2:7 in

). It is shown that compound
1
is not a suitable SSP for thin‐film fabrication using the spin‐coating process because of its incomplete decomposition at annealing temperature. However, compounds
2
and
3
seem to be promising SSPs for spin‐coating of amorphous semiconducting thin films of SnS and SnS
