Four organic-inorganic hybrid complexes ([(HL1)2SnCl 6]·2H2O (1) (L1=2-methylquinoline), [(HL2) 2(CdCl4)]·2H2O (2) (L2=5,7-dimethyl-1,8- naphthyridine-2-amine), [(H2L2)2SnCl6]2(Cl) (3), and [(H2L3)SnCl6]·2H2O (4) (L3=3,6-bis(imidazol-1-yl)pyridazine)) derived from N-containing aromatic Brnsted bases and metal(II) chloride dihydrate (tin(II) chloride dihydrate and cadmium(II) chloride dihydrate) were prepared and characterized by IR, X-ray structure analysis, elemental analysis, and TG analysis. The aromatic rings of the cations in all of the compounds are essentially planar. X-ray diffraction analysis revealed that 2-4 have 3-D network structures built from hydrogen bonds between the cations and chlorometallates. Water molecules also play important roles in structure extension in 1, 2, and 4. The arrangements of the anions and cations in their solid state are dominated by shape, size, and symmetry of the cations and the different structures of the chlorometallates as well as by hydrogen-bond interactions.

Six new CoII complexes [Co(L1)4(OH)2] (1), {[Co(L1)(H2O)4]·2ClO4}∞ (2), {[Co(L1)(H2O)4]·SiF6}∞ (3), {[Co(L1)3]·2ClO4}∞ (4), [Co(L2)Cl2]∞ (5) and {[Co(L2)2]·SiF6}∞ (6) [L1=3,6-bis(N-imidazolyl) pyridazine, L2=3,6-bis (N-benzimidazolyl) pyridazine] have been synthesized and characterized by elemental analysis, IR spectra and single crystal X-ray diffraction. Complex 1 has a mononuclear structure, while complexes 2 and 3 have 1-D chain structures. Considering the CoII centers were linked by the L1 ligands, the 3-D framework of complex 4 can be rationalized to be a {4^12.6^3} 6-c topological net with the stoichiometry uninodal net. 5 reveals a coordination 1-D zigzag chain structure consisting of a neutral chain [Co(L2)Cl2]n with the CoII centers. Complex 6 has a rhombohedral grid with a (4, 4) topology. The TGA property, fluorescent property and photocatalytic activity of complexes 1-6 have been investigated and discussed.

Abstract: Three structurally related ligands 3-chloro-6-(benzoimidazol-1-yl)pyridazine (L1), 3-chloro-6-(1,2,4-triazol-1-yl)pyridazine (L2) and 3,6-bis(imidazol-1-yl)pyridazine (L3) were designed and synthesized, and six new Zn(II), Co(II), Cu(II) and Cd(II) complexes, namely, [M(L1)2Cl2] [M = Zn (1) and Co (2)], [Cu(L2)2(NO3)2(H2O)] (3), [Cu(L2)2Cl2]∞ (4), [CuL3(CH3COO)2]∞ (5) and [CdL3(SCN)2]∞ (6) were synthesized and characterized by elemental analyses, IR spectra as well as single-crystal X-ray diffraction analysis. The analysis reveals that complexes 1, 2 and 3 have a mononuclear structure, 1 and 2 have a similar structure. Complex 3 features a 1D structure with intermolecular O–H?O hydrogen bonding interactions. Complex 4 shows a 1D chain structure with bridging Clˉ ions. Complex 5 exhibits a 1D ladder structure. The 2D framework of 6 features are rectangular grid with a (4, 4) topology. Additionally, photoluminescence properties of ligands L1, L3 and complexes 1, 2 and 6 have been studied and discussed. Graphical Abstract: Six new metal-organic complexes were synthesized and structurally characterized, complexes 1, 2 and 3 have a mononuclear structure, complexes 4 and 5 show 1D chain structure, the 2D framework of 6 has a rectangle grid with a (4, 4) topology, moreover, photoluminescence properties of ligands L1, L3 and complexes 1, 2 and 6 have been studied and discussed.

A number of 6-chloro-3-(pyrazol-1′-yl) pyridazines were prepared from 3,6-dichloropyridazine via either reaction with hydrazine followed I by reaction with appropriate reagents to develop the pyrazole or through a nucleophilic reaction with a pyrazole. So
