Two New Crystalline Organogermanate‐Based Inorganic‐Organic Hybrid Compounds

The bifunctional metalloligand bis(carboxyethylgermanium)sesquioxide, (HOOCCH 2 CH 2 Ge) 2 O 3 , was employed in the systematic high‐throughput (HT) investigation of the system Zn 2+ /(HOOCCH 2 CH 2 Ge) 2 O 3 /H 2 O/C 4 H 9 OH. Two new metal‐organogermanates Zn[(OOCCH 2 CH 2 Ge) 2 O 3 ] ( 1 ) and Zn 2 (O 3 GeCH 2 CH 2 COO) ( 2 ) were discovered that show two new structural motifs for this class of compounds. Whereas in compound 1 a formal intercalation in the structure of (HOOCCH 2 CH 2 Ge) 2 O 3 is observed, 2 exhibits a new layered structure composed of CGeO 3 and ZnO 4 unit linked by μ 3 ‐oxygen atoms. Both connectivity modes lead to dense three‐dimensional framework structures.
