摘要：

A series of 1-(2-amino-2-oxoethyl)-4-carbamoylpyridin-1-ium salts with different anions (PF6- (1), OTf- (2), BPh4- (3) and Br- (4)) have been synthesized and characterized by single crystal X-ray diffraction. The results demonstrate that the unparallel diamide-substituted pyridinium salts form a dimerized rectangular building block and a 2-D rectangular structure via N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonding (PF6- (1) and OTf- (2), respectively), a 2-D sheet structure (BPh4- (3)) via N-H center dot center dot center dot O hydrogen bonding catemers and a 2-D plate structure via N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonding catemers (Br- (4)). The effects on the hydrogen bonding motifs, building blocks and structures by the four anion species with different hydrogen bonding acceptor abilities, sizes and shapes have been discussed.
