A thermally stable pcu network based on ferromagnetic dinuclear Ni(II) units

• A pcu network based on dinuclear Ni(II) units has been hydrothermally synthesized.
• Two Ni(II) ions are bridged by two carboxylate groups in the syn-anti mode.
• The dominant ferromagnetic interactions exist between Ni(II) ions.

A pcu network based on the dinuclear Ni(II) units, [Ni2(hfipbb)2(1,3-bix)2]n (1) (H2hfipbb = 4,4′- (Hexafluoroisopropylidene)bis(benzoic Acid); 1,3-bix = 1,3-bis(imidazol-1-ylmethyl)benzene), has been hydrothermally synthesized and structurally characterized. Interestingly, the two Ni(II) cations are bridged by two carboxylate groups in the rarely-seen syn-anti mode. The magnetic data reveal the dominant ferromagnetic interactions between Ni(II) ions.
