Paniculine Hydrobromide

Abstract

CIsH3oBrNO3, Mr=388.3, triclinic, P1, a=7-999(2), b=15-549(7), c=7-929(2)A, a= 103.52 (3), fl= 105.57 (2), ),=86.89 (3) ° , V= 923.7 (6)/k 3, Z = 2, D x = 1.396 g cm -3, 2(Mo K0t) = 0.71069/~, g=22.15cm -l, F(000)=408, T=293K, final R =0-049 for 4066 observed reflections. The structure deduced by chemical and spectroscopic methods for this alkaloid is confirmed and consists of four fused six-membered rings in chair conformation. Two independent molecules in the asymmetric unit are the result of different intermolecular hydrogen bonds.
