AbstractThis paper describes the crystal structure of the azithromycin monohydrate pseudopolymorph (pseudopolymorphic forms, different solvates of the same chemical compound, azithromycin in our case) crystallised from isopropanol, solved by X-ray single crystal, and calledComparing the monohydrate and the dihydrate crystalline forms, we try to explain the role played by the solvent in the final results, and find a relation between the conformation in solution and in the crystal state conformation for the antibiotic.The crystal obtained using

The alkaline earth tricyanomethanides Mg(tcm)2 · 2H2O, Ca(tcm)2, Sr(tcm)2 ・H2O and Ba(tcm)2 · 2H2O were prepared from aqueous solutions of the respective chlorides and silver tricyanomethanide. Their IR spectra and thermal behavior are described. The crystal structures of Ca(tcm)2 and Ba(tcm)2 · 2H2O were determined by single crystal X-ray diffraction. The structure of Ca(tcm)2 is of the type found for several transition metal tricyanomethanides [1], containing two independent interpenetrating networks. Ba(tcm)2 · 2H2O has a unique crystal structure corresponding to a three-dimensional coordination polymer with nine fold coordinated Ba atoms connected by water molecules and tricyanomethanide anions.
