Abstract: | Details of the structures of two polymorphs of tris(ethylenediamine)cobalt(III) tetrathioantimonate(V), [Co(C2H8N2)3][SbS4], are reported. The first polymorph crystallizes in the orthorhombic space group Pna21, whereas the second polymorph belongs to the tetragonal space group P42bc. Both structures contain octahedral [Co(en)3]3+ cations (en is ethylenediamine) and tetrahedral [SbS4]3− anions, which are interconnected via various N—H...S hydrogen bonds to form two different types of three‐dimensional network. |
