Abstract

Single crystals of EA[Q(NO₂)₂O₄] · 4H₂O (EA = Ca. Sr) were grown in aqueous silicagel. Ca²⁺ has CN 8. It is surrounded by 4 oxygen atoms of two bis-chelating [C₆(NO₂)₂O₄]^2- ions and 4 water molecules, which form a distorted, bi-capped trigonal prism. Sr²⁺ is coordinated similarly, with an additional water molecule joining the coordination sphere to yield CN 8+1. Corrugated chains extending along [010] and consisting of EA²⁺ and nitranilate ions are the main feature of the crystal structure. Adjacent chains are interlinked by hydrogen bonds.
