The Electronic Structure and the Chemical Bonding in NiO and La 2 NiO 4 Crystals. A Comparison with CuO and La 2 CuO 4
Modelling from quantum chemical data of the chemical bonding in NiO and La 2 NiO 4 crystals comparatively to CuO and La 2 CuO 4 , is proposed. The increase of the ionicity degree of the Ni(II)–O bonding in comparison with Cu(II)‐O bonding is observed. The covalency is low and equally distributed in...
