(CATENA-(MU(N,S)-NCS)[NI(MEDIEN)(NCS)]) - A NEW 1D NICKEL(II) COMPLEXWITH BRIDGING THIOCYANATO LIGANDS IN CIS POSITION - CRYSTAL-STRUCTUREAND MAGNETIC-PROPERTIES

The mu(N,S) thiocyanato nickel(II) monodimensional complex, {catena-(m u(N,S))[Ni(Medien(NCS)]} (1) where Medien = N-2-methyldiethylenetriami ne, has been synthesized and characterized. The crystal structure of t his 1D complex has been solved by Patterson synthesis and refined by f ull-matrix least-squares methods. {catena-(mu(N,S))-NCS)[Ni(Medien)(NC S)]} is the second reported structural example of a nickel(II) chain i n which the neighboring nickel(II) ions are linked by thiocyanato brid ging ligands in a cis geometry. Magnetic susceptibility data, measured from 5 to 300 K show ferromagnetic behavior. These data were fitted t o the de Neef equation, giving the parameters 2l 1.92 cm(-1), g = 2.18 .
