, p. 9006 - 9014 (2015)
Atomically flat, terraced H-Ge(111) was prepared by annealing in H2(g) at 850 °C. The formation of monohydride Ge-H bonds oriented normal to the surface was indicated by angle-dependent Fourier-transform infrared (FTIR) spectroscopy. Subsequent

A series of tris(pyrazolyl)alkane (RCTp) scorpionate ligands of the type RCTp3-R′ (R=Me, nBu, SiMe3; R′=H, Me, Ph, iPr, tBu) were synthesized and their ability to coordinate methylmagnesium moieties was examined. The reaction of Mg(AlMe4)2 with neutral proligands HCTp3-Ph or Me3SiCTp3-Me, containing a non-innocent backbone methine moiety, led to deprotonation/rearrangement and SiMe3/AlMe3 exchange to afford [(Me3AlCTp3-Ph)2Mg] and [(Me3AlCTp3-Me)Mg(AlMe4)], respectively, with monoanionic tripodal ligands. Treatment of sterically less demanding RCTp3-R′ with Mg(AlMe4)2 produced isostructural dicationic “metal-in-a-box” complexes of the type [(RCTp3-R′)2Mg][AlMe4]2 (R=Me, nBu; R′=H, Me). Utilization of the superbulky ligands MeCTp3-Ph and MeCTp3-tBu gave monocationic complexes [(MeCTp3-Ph)MgMe][AlMe4] and [(MeCTp3-tBu)MgMe][Al2Me7] as separated ion pairs. The reaction of Mg(AlMe4)2 with nBuCTp3-Ph led to the formation of the dimagnesium complex [{(nBuCTp3-Ph)Mg(AlMe4)}2(μ-CH3)], which features a bridging methyl moiety and terminal η1-coordinated tetramethylaluminato ligands. Isopropyl-substituted ligand MeCTp3-iPr emerged from further fine-tuning of the steric and electronic parameters and, upon reaction with Mg(AlMe4)2, gave (MeCTp3-iPr)Mg(AlMe4)2; this represents the first example of a magnesium bis(alkyl) complex with an intact RCTp3-R′ ligand. The exact ligand cone angles Θ° of all magnesium complexes were determined according to the mathematical analysis developed by Allen et al. [J. Comput. Chem. 2013, 34, 1189–1197].

Page/Page column 8, (2008/06/13)
The invention provides magnesium S-omeprazolato compounds according to formula (I): [in-line-formulae][Mg(solva)x(solvb)y][Mg(S-omeprazolato)3]2.(solvc)z??(I), [/in-line-formulae] pharmaceutical compositions and processes of making the same. In formula (I), solva, solvb, and solvc represent solvent molecules where x and y are independently selected from integers 0 to 6, the sum of which is 4 or 6, while z is a positive rational number from 0 to 6. The compounds are useful for the treatment of gastric acid related conditions and the inhibition of gastric acid secretion.
