Abstract


This article was prepared by the hydrothermal synthesis method , respectively a novel boron polyoxometallate and three novel transition metal complexes . By infrared spectroscopy , Raman spectroscopy and X-ray single crystal diffraction means its characterization and crystal structure determination . (1 ) by hydrothermal synthesis of a new type of organic tetraborate polyoxometalates : (H 3 NCH 2 CH 2 NH 3 ) [B 4 O 5 (OH) 4 ]. The compound belongs to the monoclinic system , space group C2 / c . Compound molecules from the protonated ( H 3 All NCH 2 < / sub> the CH 2 < / sub > ! NH 3 < / sub >) 2 < / sup> B O 5 ( OH ) 4 < / sub >] 2 - with anions . Various isolated the [ B of 4 the O 5 ( OH ) 4 ] 2 - < / sup > through hydrogen bonding , formation of pore structure of the anion skeleton . Protonated ( H 3 < / sub > the NCH 2 CH 2 < / sub> NH 3 < / sub >) 2 through the hydrogen bonding interactions are filled in the pores of the anion formed . (2 ) by hydrothermal synthesis of two thiourea ligand complexes : [Co (H 2 NCSNH 2 ) 4 ] Cl 2 , [Ni (H 2 NCSNH 2 ) 4 ] Cl 2 . The two compounds are tetragonal space group P4 (2) / n and I4 . Connected to form a three-dimensional supramolecular structure through hydrogen bonding between the metal of the two compounds in the structural unit polyhedron . Wherein the three - dimensional structure , presence of thiourea ligands around the formed pores . ( 3 ) by Hydrothermal Synthesis of a new nickel complexes Ni ( C 6 < / sub > N 4 the H 18 < / sub >) ( C < sub> 3 N 2 H 9 )] Cl 2 · H 2 O. The complex belongs to the orthorhombic system , space group Pbca with . The complex molecule by a symmetrical structure unit [ Ni ( the C 6 < / sub> N 4 < / sub> H 18 < / sub >) (C 3 < / sub> N 2 H 9 )] 2 , two chlorine atoms and a lattice water . Chloride ions and lattice water are connected by hydrogen bonds and structural units constitute a solid three-dimensional supramolecular network structure . (4) the hydrothermal synthesis of inorganic - organic hybrid materials were also discussed .
