High- versus low-spin Ni2+ in elongated octahedral environments: Sr2NiO2Cu2Se2, Sr2NiO2Cu2S2, and Sr2NiO2Cu2(Se1–xSx)2
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 NiO4Se2environment with D4hsymmetry, adopt a high-spin configuration and carry localized magnetic moments which order antiferromagne...
