Crystals of 2-amino-6-fluoro-1,3-benzothiazole, C7H5FN2S, have an amphiphilic layer-like structure. Each amino substituent donates two protons to hydrogen bonds and accepts one. The ring N atoms accept one proton. The F atoms are not involved in any hydrogen bonds.

The repeating unit in this polymeric structure involves both thiourea ligands and one
2-fluorobenzoate ligand. The Pb atom is coordinated by four O atoms from three
2-fluorobenzoate ligands and four S atoms from four thiourea ligands. The Pb
Pb separation is 3.74 Å. The
many hydrogen bonds include three-centered hydrogen bonds involving C-F bonded F atoms.

Crystals of aqua(glutamato)cadmium hydrate, [Cd(C5H7O4)(H2O)].H2O, are orthorhombic, space group P212121. The compound is nearly isostructural with the corresponding zinc and copper complexes. The coordination about the cadmium is a distorted octahedron, with Cd-O1 2.282 (3), Cd-O2 2.254 (3), Cd-O3 2.303 (2), Cd-O4 2.449 (2), Cd-O5 2.255 (2) and Cd-N 2.290 (2) Å.
