Two New Crystalline Organogermanate‐Based Inorganic‐Organic Hybrid Compounds

Abstract

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 * Prof. Dr. N. Stock

Structural features of two novel alluaudite-like arsenates Cd1.16Zn2.34(AsO4)1.5(HAsO4)(H2AsO4)0.5 and Cd0.74Mg2.76(AsO4)1.5(HAsO4)(H2AsO4)0.5

“…Because of the broad band shape, As—O tetrahedral stretching vibrations and lattice modes are superimposed in the low-energy region of the spectrum. The infrared spectrum clearly shows the presence of broad O—H stretching and bending vibrations centred around 3236, 2300/1310 cm −1 and 3210, 2390/1390 cm −1 for 1 and 2 respectively [63]. According to the d–ν correlation for hydrogen bonds this wavenumbers are in very good agreement with the refined H⋯O bond lengths [64].…”

Cu42Ge24Na4—A Giant Trimetallic Sesquioxane Cage: Synthesis, Structure, and Catalytic Activity

“…Indeed, the whole complex of 1 is built up of two similar cage units of unprecedented Cu 21 Ge 12 -nuclearity. An isolation of such metal-rich (the M/Ge ratio exceeds 1/1) product has never been reported for any metallagermaniumsesquioxanes [20][21][22][23][24][25][26][27][28][29][30]. In terms of topology, the spherical shape of cage-like components of product 1 could be compared only to non-dimeric Cu(I)-based silsesquioxane reported by the team of Prof. Zhu and Prof. Roesky [31].…”

“…It is ultimately surprising but to the best of our knowledge germanium sesquioxane ligands that are the closest analogues of silsesquioxanes, have been scarcely studied in the context of a possible molecular design of metallacomplexes so far. We could mention here only the use of (i) bis(carboxyethyl)germanium sesquioxide [20][21][22][23][24][25][26][27] in hydrothermal reactions and (ii) PhGe(OMe) 3 [28,29] in the self-assembly synthesis.…”

Synthesis and Characterization of the Organogermanate‐Based Inorganic‐Organic Hybrid Compound Ca2[(OOCC2H4Ge)2O3]2·3H2O

“…Combined with trivalent lanthanide salts organogermanate cluster organic frameworks containing {Nd 8 Ge 12 } or { Ln 11 Ge 12 } units have been derived 18. Using the divalent metal ions Cd 2+ , Pb 2+ and Zn 2+ four metal organogermasesquioxanes were obtained 19,20 . Yang et al synthesized Cd 1.5 [(OOCCH 2 CH 2 Ge) 3 O 5 ] and Pb[(OOCCH 2 CH 2 Ge) 2 O 3 ] 19.…”

“…Yang et al synthesized Cd 1.5 [(OOCCH 2 CH 2 Ge) 3 O 5 ] and Pb[(OOCCH 2 CH 2 Ge) 2 O 3 ] 19. Recently, two compounds were published containing Zn 2+ ions 20. Applying our high‐throughput methodology21–23 the system Zn 2+ / (HOOCCH 2 CH 2 Ge) 2 O 3 / H 2 O / 2‐propanol was investigated and the fields of formation of Zn[(OOCCH 2 CH 2 Ge) 2 O 3 ] and Zn 2 (O 3 GeCH 2 CH 2 COO) were established.…”
