High- vs. low-spin Ni2+ in elongated octahedral environments: Sr2NiO2Cu2Se2, Sr2NiO2Cu2S2 and Sr2NiO2Cu2(Se1-xSx)2

Abstract:

Sr2NiO2Cu2Se2, comprising alternating [Sr2NiO2]2+ and [Cu2Se2]2– layers, is reported. Powder neutron diffraction shows that the Ni2+ ions, which are in a highly elongated NiO4Se2 environment with D4h symmetry, adopt a high-spin configuration and carry localized magnetic moments which order antiferro...
