Abstract
Abstract
Four complex metal antimony tartrates have been synthesized in single crystal form by slowly evaporating aqueous solutions of potassium antimony tartrate (tartar emetic) and metal nitrates or chlorides. Crystal structures of these compounds all contain infinite layers formed by linking antimony tartrate dimers with M–O bonds, with M = Li, La, Ce or Nd. Dehydration of the La and Ce compounds at elevated temperatures led to new layered structures via single-crystal to single-crystal transformations.

Abstract
Abstract
Seven complex metal antimony tartrates have been synthesized in single crystal form by slowly evaporating aqueous solutions of potassium antimony tartrate (tartar emetic) and divalent metal nitrates or perchlorates. Crystal structures of these compounds all contain infinite chains formed by linking antimony tartrate dimers with divalent metal ions. While infinite chains of antimony tartrate dimers bridged by single Zn2+ ions or by double Mg2+ ions were reported previously, new types of chains with alternating single and double bridging cations are observed in this work.
