Cyanoacetamidobetaine—A Zwitterionic Nitrile Derivative

open access: yesChemistryOpen, EarlyView.
The reaction of sodium dicyanamide with betainium chloride in aqueous solution affords N‐cyano‐2‐(trimethylammonio)acetaminide (cyanoacetamidobetaine). Single crystal X‐ray diffraction reveals a monoclinic structure comprising a trimethylammonium head group connected to a cyanoacetaminide unit via a methylene bridge.

Rb4CuSb2X12 (X = Cl, Br) as Novel Vacancy‐Ordered Quadruple Perovskites

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The vacancy‐ordered quadruple perovskites Rb4CuSb2X12 (X = Cl, Br) were crystallized from hydrohalic acid. Their crystal structures can be interpreted as new distortion variants of the perovskite structure with ordered vacancies. The electronic structure of Rb4CuSb2Br12 shows that the Br and Sb states form the valence band and the upper conduction band.
