4-(5-Chloro­thio­phen-2-yl)-1,2,3-selenadiazole

In the title compound, C₆H₃ClN₂SSe, the selenadiazole and chloro­thio­phene rings are almost coplanar [dihedral angle = 5.24 (15)°]. In the crystal, C—H...N inter­actions link the mol­ecules into chains extending along the b-axis direction. C—H...π inter­actions also occur.

cis-Chlorido(ethyl­amine)­bis­(propane-1,3-diamine)­cobalt(III) dichloride

In the title compound, [CoCl(C₂H₇N)(C₃H₁₀N₂)₂]Cl₂, the Co^III ion has a distorted octa­hedral coordination environment and is surrounded by four N atoms in the equatorial plane, with the other N and Cl atoms occupying the axial positions. The crystal packing is stabilized by N—H...Cl hydrogen bonds, forming a layered arrangement parallel to (1-10).
