Synthesis and structural characterization of a calcium coordination polymer based on a μ 3 -bridging tetradentate binding mode of glycine#

Preparation and properties of a calcium(ii)-based molecular chain decorated with manganese(ii) butterfly-like complexes

The room temperature reaction of [Mn₂O₂(bipy)₄](ClO₄)₃ (bipy = 2,2′-bipyridine) with Ca(CHCl₂COO)₂ in methanol produced a yellow crystalline material.

A new compound in kidney stones? Powder X-ray diffraction study of calcium glycinate trihydrate

The present identification of a new compound in kidney stones is relevant in clinical practice. Here, poly[[di-μ-aqua-bis(glycinato-κ2N,O)calcium(II)] monohydrate], {[Ca(C2H4NO2)2(H2O)2]·H2O}n, has been identified in a possible kidney concretion, although it could be a `false calculus' associated with Munchausen syndrome. The crystal packing is characterized by an infinite zigzag chain of Ca atoms in [Ca(OW)4O2N2] (OWis a water O atom) square antiprisms, sharing edges formed by water molecules. An uncoordinated water molecule interconnects the parallel chains in a three-dimensional hydrogen-bonding scheme. Similarities between the trihydrate and the monohydrate are described.
