Two polymorphs of tris­(ethyl­ene­diamine)­cobalt(III) tetra­thio­anti­monate(V)

Two polymorphs 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.

A two-dimensional Cu^I framework incorporating the 1-phenyl-1H-1,2,3,4-tetra­zole-5-thiol ligand

The coordination polymer [Cu(ptt)]_n (ptt is 1-phenyl-1H-1,2,3,4-tetra­zole-5-thiol­ate) has been prepared under solvothermal conditions. Its structure features two-dimensional layers which lie parallel to the (100) plane.
