Syntheses, Crystal Structures, UV‐Vis Spectra and First NMR Spectra of New Potassium Salts of Chalcogenogermanates

Abstract

Abstract Single‐crystalline K + salts of chalcogenogermanate anions and their corresponding hydrates have been prepared. K 4 [GeS 4 ] ( 1 ), K 4 [GeSe 4 ] ( 2 ), [K 4 (H 2 O)][GeS 3 (OH)] ( 3 ), [K 4 (H 2 O) 4 ][GeSe 4 ] ( 4 ), [K 4 (H 2 O) 2 ][GeTe 4 ] ( 5 ) and [K 4 (H 2 O) 3 ][Ge 2 Se 6 ] ( 6 ) were characterized by means of X‐ray diffractometry and optical absorption spectroscopy. Additionally, first NMR‐spectra of chalcogenogermanate salts are presented for 4 – 6 .
