摘要：
Single crystal X-ray analysis of an aminoethyl mannopyranoside, namely, N-(benzyloxycarbonyl)aminoethyl-2,3,4,6-tetra-O-benzoyl-alpha-D-mannopyranoside (1), shows that the compound crystallizes in the monoclinic space group P2(1), with two molecules in the unit cell. The mannopyranoside unit adopts a distorted C-4(1) conformation. An analysis of the intermolecular interactions reveals a tandem network of N-(HO)-O-.., C-(HO)-O-..., and C-H(...)pi interactions responsible for stabilizing the crystal lattice.
