标题:Structural And Vibrational Investigation Of 2-Amino-4-Nitropyridine Crystal
摘要:The X-Ray Structure Of 2-Amino-4-Nitropyridine Was Determined At Room Temperature. The Crystal Belongs To The P2(1)/c Space Group Of The Monoclinic System (Z = 4,A = 6.7290(10),B = 10.946(2),C = 9.060(2) Angstrom,Beta = 100.03(3) Deg) And Is Built Of Layers Parallel To The (102) Crystallographic Plane. The Molecules In The Layer Are Joined Into Centrosymmetric Dimers By Two N-H ... N Hydrogen Bonds (N ... N Distance = 3.011(3) Angstrom),Which Form Rings Of Ci Symmetry. The Other N-H Bonds Of The Amino Groups Are Involved In N-H ... O Hydrogen Bonds With The Oxygen Atoms Of The Nitro Groups (N ... O Distance = 3.054(3) Angstrom). These Hydrogen Bonds Join The Dimers Into An Infinite Plane. The Powder Ir And Raman Spectra (4000-80 Cm(-1)) Were Measured For Normal And Deuterated Crystals And Are Discussed With Respect To The Crystal Structure. The N-H Stretching Vibrations Behave As The Stretching Vibrations Of Two Almost Independent Hydrogen Bonds. Strong A(G)-A(U)-Type Splitting Is Observed For The Stretching Vibrations Of The N-H ... N Type Hydrogen Bonds. (C) 1997 Elsevier Science B.V.
