A novel two-dimensional cadmium polymeric aminonaphthalene sulfonate and its application in the synthesis of CdS materials

A new mixed-ligand complex, [CdL(bipy)(CH3OH)(NO3)](n) (1), (HL = 4-amino-1-naphthalene sulfonic acid and bipy = 4,4'-bipyridine) could be achieved by combining (d(10) Cd2+ to HL and bridging ligand 4,4'-bipy. The structure is characterized by X-ray single-crystal diffraction. 4-amino-1-naphthalene sulfonate and 4,4'-bipyridine act as bridging ligands, linking two adjacent Cd-II atom to form a two-dimensional coordination polymer, respectively N-H center dot center dot center dot O hydrogen-bonding interaction between these networks to form the face-to-face three-dimensional architecture. By carrying out the reaction of polymeric cadmium naphthalene sulfonate with Na2S in the presence of sodium hydroxide, scale-like CdS materials have been obtained. The structure has been characterized by scanning electron microscopy and powder X-ray diffraction.
