ELECTRON-PARAMAGNETIC RESONANCE STUDY OF THE REACTION OF GROUND-STATE AL ATOMS WITH NH3 IN A ROTATING CRYOSTAT
An electron paramagnetic resonance spectroscopic study of the reaction of ground-state Al atoms with NH3 in adamantane at 77 K on a rotating cryostat has demonstrated the formation of three mononuclear Al-NH3 complexes, Al(NH3)4 (A), HAlNH2 (B), and Al(NH3)2 (C). These species have the following mag...

| description | An electron paramagnetic resonance spectroscopic study of the reaction of ground-state Al atoms with NH3 in adamantane at 77 K on a rotating cryostat has demonstrated the formation of three mononuclear Al-NH3 complexes, Al(NH3)4 (A), HAlNH2 (B), and Al(NH3)2 (C). These species have the following magnetic parameters: aAl = 786.3 ± 0.22 MHz, aN = 23 ± 0.08 MHz, and g = 1.9997 ± 0.0001 for Al(NH3)4, aAl = 922.5 ± 0.41 MHz, aH = 228.7 ± 2.00 MHz, aN = 27 ± 2.0 MHz, aH(1) = 27 ± 2.0 MHz, and g = 2.0003 ± 0.0002 for HAlNH2, and a∥(Al) = 131.5 MHz, a⊥(Al) = ca. 20 MHz, and g∥ = gperp; = 1.999 for Al(NH3)2. HAlOH (D) is also formed in this system from adventitious H2O and has the parameters aAl = 911.3 ± 1.06 MHz, aH = 286.4 ± 3.7 MHz, and g = 1.9998 ± 0.0004. |
