Abstract

The compound [Ni₃(tppz)₂(NCS)₂(H ₂O)₄](NO₃)₄•4H₂O [tppz = 2,3,5,6-tetrakis(2-pyridyl)pyrazine and NCS = thiocyanate ligand] consists of trimeric units, where the three Ni^II cations are linked by two bis-tridentate tppz ligands. This compound crystallizes in the monoclinic space group C2/c, with Z = 4, a = 25.1116(12) Å, b = 10.8127(5) Å, c = 25.2294(13) Å, and β = 116.856(5)°. The crystal structure is in good agreement with the antiferromagnetic interactions because of unidirectional coupling through the tppz ligands.
