In this paper, solvothermal conditions, using homemade flexible 1,2 - bis (BTA) ethane (L1), 1,3 - bis (BTA) propane (L2), 1,4 - pair (BTA) butane (L3) and 1,6 - bis (benzotriazole) hexane (L4) as bridging ligand to halogen ion as the second bridging ligand, respectively, and d10 transition metals Cu (I) and Cd (II) were synthesized 10 novel structure doped compounds were identified as: {CdI2] 2 (L1) 2} (1), {[CdBr2] 3 (L1) 2}. (2), {[CdI2] (L2)} n. (3), {[CdBr2] (L3)} n. (4), {[CdBr2] 2 (L4) 2}. (5), {[CdI2 ] 4 (L4) 4} n. (6), {[CdCI2] 5 (L1) 2). (7), {[CuCl] 2 (L4)} n. (8), {(HETA) [(Cu6I7 ) (ETA) 2]} n. (9) and {K (Cu6Br7) (L4)}. (10), using X-ray diffraction for crystal structure for them to determine. Compounds 1-7 for the series Cd (II) compounds are monoclinic. Compounds 1, 2 and 7 are C2 / c space group; compounds 3 and 4 are P2 (1) / c space group; compound 5 and 6, respectively, corresponding to P2 (1) In and space group Cc. Compounds 1 and 7, respectively, in addition to zero-dimensional and two-dimensional structure, the remaining compounds were one-dimensional structure. Compound 1 is [Cdl2 (L1)] 2 dual-core unit zero-dimensional structure; compound 2 is μ2 bridging ligands L1 in one dimension [CdBr2] inorganic chains form one-dimensional organic and inorganic chain structure; compounds 3 and 4 are made from organic bridging ligands adopt μ2 mode connection [CdX2] inorganic units and the formation of an infinite chain structure; compound 5 in the presence of both [Cd-Br-Cd-Br] inorganic diamond structure and [Cd-L4- Cd-L4] dual-core unit, alternately connected to form a two-dimensional infinite chain structure; compound 6 first by independent Cd1, Cd2, Cd3 and Cd4 connection L4 ligands form a parallelogram [Cd4 (L4) 4] ring structure and then pass between adjacent ring structure another independent ligand L4 connected to form one-dimensional infinite banded structure; compound 7 by μ2 bridging ligands L1 by the absence of cubane units [Cd3Cl4] constructed one-dimensional band structure and the formation of inorganic-dimensional network structure. Compounds 8-10 are the first 1,6 - bis (benzotriazole) hexane (L4) as a ligand formed Cu (I) compounds. Compound 8 is tetragonal, I4 (1) / a space group; compounds 9 and 10 are monoclinic, respectively C2 / c and P2 (1) / m space group. Compound 8 is a μ4 bridged ligands L4 one-dimensional [CuCl] n-dimensional structure is formed of inorganic chain; compounds 9 and 10 for the first time a novel [Cu6IX7] nn-(X = C1, Br) anion chain wherein compound 9 by a novel one-dimensional organic anion chain [(Cu6I7) (ETA) 2] nn-and protonated organic cation HETA composition, while compound 10 is a one-dimensional [Cu6Br7] nn-anion chain with seven-coordinated K atom to form a two-dimensional [KCu6Br7] layered structure, and L4 bridged ligands used μ4 connected to the layered structure. In this paper, the ligand L1-L4 and compounds 1-10 were characterized by elemental analysis, thermal gravimetric analysis, infrared spectroscopy, X-ray powder diffraction and fluorescence properties of semiconductors such as a comprehensive physical and chemical properties, but also for the weak interaction present in the compound action and the conformation of the ligand was studied.
