文摘Coordination complexes derived thiosemicarbazone ligands were designed to exhibit the potential factors to influence the molecular packing. The aromatic group 4,5 diazafluorene can form strong hydrogen bonds with the lattice water molecules from which connect the molecules aggregating into a one dimensional screw chain. It seems that the existence of those hydrogen bonds is essential for the molecules crystallized in noncentral space group and exhibiting obviously SHG efficiency.
