Synthesis and X-ray crystallographic structure of Ga4(OH)6(3-ButpzH)10I6·2MeCN: a quasi double heterocubane

Solution structural characterization of an array of nanoscale aqueous inorganic Ga13−xInx (0 ≤ x ≤ 6) clusters by 1H-NMR and QM computations

“…This assignment is in agreement with M–(μ 2 -OH)–M bridges reported for other Group 13 complexes. 5 , 7 – 10 …”

“…This assignment is in agreement with M-(m 2 -OH)-M bridges reported for other Group 13 complexes. 5,[7][8][9][10] Due to the simplicity of Ga 7 In 6 , the spectra and analysis for this cluster make a good basis for determining a suitable theoretical method for computational elucidation of the m 2 -OH signals. Most importantly, computations performed without explicit counterions in the structure predict the exact opposite ordering of the internal and external m 2 -OH signals.…”

Single-Ion versus Dipolar Origin of the Magnetic Anisotropy in Iron(III)-Oxo Clusters: A Case Study

“…To our knowledge, the six‐membered cyclic structure of 2 is unprecedented among oxo‐bridged gallium( III ) clusters. These include the trimeric μ 3 ‐oxo‐centered carboxylate [Ga 3 (O)(O 2 CPh) 6 (4‐Me‐py) 3 ] + ,19a the tetranuclear complex [Ga 4 (OH) 6 (3‐ t Bu‐Hpz) 10 ] 6+ with a “butterfly” core,19b and the octagallium( III ) cluster [Ga 8 (pz) 12 O 4 Cl 4 ] (Hpz=pyrazole) 20. In the latter, four penta‐coordinated gallium( III ) ions are connected to an inner Ga 4 O 4 cubane core through μ 4 ‐oxo and pyrazolato bridges.…”

Synthesis and structural characterization of gallium and indium complexes obtained from redistribution reactions of mixed chalcogen-imidodiphosphinate ligands

“…Moreover, the formation of donor/acceptor complexes of GaCl 3 and InCl 3 is largely limited to adduct formation with ligands containing hard donor atoms such as O or N (crown ether, DMSO, HMPA, pyridine, etc.) [2][3][4]. Although examples of gallium and indium tris-chelate complexes comprising symmetric and asymmetric imidodichalcogenodiphosphinate backbones are known [5,6], there are only a few examples of mono-chelate complexes bearing such types of ligands, and even less with asymmetric ligands [7,8].…”
