Magnetic property of a 1D triazacycloalkanes Ni(II) with chiral helical structure complex {[Ni[12]aneN3](μN,S-SCN)(SCN)}n

A novel chiral helical triazacycloalkanes 1D complex {[Ni[12]aneN3](μN,S-SCN)(SCN)}n (1) ([12]aneN3 = 1,5,9-triazacyclododecane) was synthesized and characterized by X-ray single-crystal diffraction, elemental analysis, IR, electronic spectra and magnetic properties. The magnetic behaviour reveals a ferromagnetic interaction between Ni(II) ions through μN,S-SCN− bridges, 2J = 5.072 cm−1, g = 2.159.
