| According to ideas of molecule designing, Cu(II), Fe(II) and Ni(II) were selected as templates, Benzotriazole (BTAH), KSCN and 4-cyano-pyridine (4-CNPy) as building blocks. Crystals of 1-D chains, 3-D networks polymers, 3-D hydrogen-bonded frameworks were synthesized and characterized. Potential applications were also investigated for tailored solar radiation coatings and conductive coatings. The major contributions of the paper are shown as follows:1. 1-D chains, 3-D network polymers and 3-D hydrogen-bonded frameworks were synthesized for the first time.1-D chain coordination polymers of [CuII (BTAH)2(SCN)2]-2H2O and [Cu II (CNPy)2(SCN)2] were synthesized by conventional solution routes. Each Cu( II) ion is located in the center of distorted octahedron, in which SCN" conducts as bidentate ligand to form N-Cu bond and S-Cu bond. And N of SCN" is still of stronger coordination capability than S in coordination polymers.3-D network polymer of [FeII(C5H4NCOO)2]n was synthesized by the reaction of FeCl3-6H2O with 4-CNPy and KSCN under solvothermal conditions. The slow hydrolysis of 4-CNPy to the isonicotinate group is very crucial for the synthesis of [Fe II(C5H4NCOO)2]n. In the crystal structure, the horizontal positions are occupied by four O atoms from four C5H,,NCOO" groups. The two vertical sits are available for coordination of N atoms of two C5H4NCOO" groups. Chair conformation eight-membered rings of two carboxyl-bridged metal FeII centers extend along 3-Ddirections, thus resulting in markedly rhombus channels.Orange red block crystals of organic-inorganic hybrid materials [Fe '" 2O(OH)( C5H4NCOO)SO4] were obtained by using the reaction of FeCl3-6H2O with 4-CNPy, KSCN, and H2O2 under solvothermal conditions. The SO42' and C5H4NCOO, were supposed to result from oxidation of SCN group and hydrolysis of CN group of 4-cyanopyridine under the solvothermal conditions, respectively. The crystal structure was determined by X-ray diffraction to reveal a three-dimensional covalent framework, which was constructed with coordinated octahedra of Fem(l) and Fein(2) centers, coordinated tetrahedra of S^ centers, and tridentate isonicotinate ligands. The crystal structure of [Fe,O(OH)( C5H4NCOO)SO4] is considered to be constructed with [Fem 2O(OH)( C5H4NCOO)]2", layered polymeric coordination complex cations and [SO4]2" tetradendate oxide anions. For more clarity, however, the 3-D covalent framework will be described as coordination of [Fe2O(OH)SO4]+ inorganic cationic 'layers' with (C5H4NCOO)" organic anionic ligands. There are infinite channels with the size of about 9 X 6 A along the b direction.Three kinds of 3-D hydrogen-bonded networks [Mn(C5H4NCOO)2] -4H2O with the same structure were synthesized by solvothermal reactions, in which Cu( II), Fe( II) and Ni( II) selected as center cations and isonicotinate as monodentate ligand. It was shown that coordination activity of the pyridyl nitrogen atom to M2+ is stronger than carboxyl oxygen atom of isonicotinate ligand. Each M2+ center is octahedrally coordinated by four water molecules in a regular square and two isonicotinate groups in trans position via pyridyl nitrogen atoms. The complex molecules pack to construct an infinite 3-D framework through hydrogen bondings between coordinated water molecule and uncoordinated carboxyl oxygen atom.2. It was shown that solution reactions and solvothermal reactions are often sensitive to certain experimental parameters, such as temperature, solvent, stoichometry, PH level and procedure of adding reactants. This paper also illustrated how these factors played a vital role in affecting the products formation, theirstructures and topologies.3. The effects of the procedure of adding reactants on the coordination modes of thiocyanato group in homogeneous copper thiocyanates are first explained by non-associated electrolytic solutions theory.4. A new method of characterizing the absorption ability to solar radiation of the colored powdered materials was raised. It was shown that under certain temperatureand in the 2...
