Komplexe mit substituierten 2,5-Dihydroxy-p-benzochinonen: EAC6(C6H5)2O4 · 4 H2O (EA = Sr2+, Ba2+)

Complexes with Substituted 2,5-Dihydroxy-p-benzochinones: EAC₆(C₆H₅)₂O₄ · 4 H₂O (EA = Sr²⁺, Ba²⁺) Single crystals of the isotypic compounds EAC₆(C₆H₅)₂O₄ · 4 H₂O were grown in aqueous silicagel. EA²⁺ has CN 8. It is surrounded by four water molecules and four oxygen atoms of the bis-chelating polyporate dianions. Thereby folded chains are formed which are interlinked by hydrogen bonds. Thus building up corrugated layers with the phenyl substituents almost perpendicular to the layer plane. The layer stacking provides that they can engage into another.
