Abstract
C 4 H 11 NO 3 , orthorhombic, Pna 2 1 , a = 8.807(6) Å, b = 8.872(7) Å, c = 7.709(7) Å, V = 602 Å 3 , Z = 4, D c = 1.335, D m = 1.335 g cm −3 (in butyl alcohol), λ (Cu Kα ) = 1.5418 Å. The structure was solved using MULTAN and refined by the full matrix least-squares method to a final R value of 0.080. The central carbon atom is coordinated tetrahedrally by the carbon atoms of hydroxymethyls and the nitrogen atom of an amino group. The NH 2 ∓ C ∓ (CH 2 OH) 3 tetrahedra show marked departures from a regular tetrahedron.Keywords
