Bidentate Phosphine Oxides as Ligands to form Ga^III Shell Complexes. [Ga(CH₂(P(O)Ph)₂)₃]³⁺: Synthesis, Structural and Spectroscopic Study

Abstract

The tri-cationic shell gallium complex [Ga(CH 2 (P(O)-Ph) 2 ) 3 ] 3+ containing three neutral diphosphine oxide ligands has been synthesized and structurally characterized by using X-ray crystallography, mass spectrometry, and 1 H, 13 C, 31 P, and 71 Ga NMR spectroscopy. The ligands form three equivalent six-membered chelate cycles to give

Applications of nuclear shielding

“…The ligands form three equivalent six-membered chelate cycles to give an idealised octahedral environment around the Ga 3 þ ion. 208 Transparent glass-ceramics were prepared in the Ga 2 S 3 -GeS 2 -CsCl pseudoternary system using appropriate heat treatment time and temperature. In situ X-ray diffraction at the heat treatment temperature and 133 Cs and 71 Ga solid-state NMR were performed in function of annealing time to understand the crystallisation process.…”
