“…Here again, the role of the anions is often overlooked in the usual narrow focus on the bridging ligand and careful studies on anion-structure correlation are rare. 87 A crucial anion-influence is the competition of coordination ability between the counter anions and the organic bridging ligands to the metal. Non-coordinating anions like ClO 4 À or BF 4…”

“…Recently, it was reported that silver(I) complexes with mi form a onedimensional chain structure in the crystal, and therefore it is expected that coordination compounds with mi form unique coordination networks. [30] Scheme 2. Molecular structure of 2-methylisothiazol-3(2H)-one.…”

A dinuclear copper(II) complex, [{Cu II Cl(O-mi)} 2 (μ-Cl) 2 ] [mi = 2-methylisothiazol-3(2H)-one], has been synthesized and its molecular structure in the solid state determined by single-crystal X-ray analysis. The crystal consists of centrosymmetric dinuclear copper(II) units in which each copper(II) ion is doubly bridged by two chloride ions and has a slightly distorted square-planar geometry with a terminal chlorido ligand and a terminal mi ligand coordinated through the oxygen atom. The dinuclear units stack one on top of another to form a one-dimensional two-leg ladder structure. The magnetic susceptibility of the powder was measured in the temperature range 3.0-302 K. It was found that there are ferromagnetic interactions along the rung (in the same direction

“…It is an intriguing and challenging task to construct coordination compounds deliberately, because the self-assembly process is influenced by many factors, such as the organic ligands used (Rowsell & Yaghi, 2005), the metal coordination geometry (Qin et al, 2012), the inorganic counter-ions (Kato et al, 2008), the reaction temperature (Dong et al, 2007), the pH value (Hilbert et al, 2014), the solvent system (Bu et al, 2002) etc. Among these factors, the choice of the organic spacer has the greatest influence on determining the type and topology of the product (Bai et al, 2012;Vrdoljak et al, 2010).…”

A potentially pentadentate hydrazone ligand, N'-[1-(pyrazin-2-yl)ethylidene]nicotinohydrazide (HL), was prepared from the condensation reaction of nicotinohydrazide and acetylpyrazine. Reactions of HL with MnCl2, Mn(CH3COO)2 and Cd(CH3COO)2 afforded three metal complexes, namely dichlorido{N'-[1-(pyrazin-2-yl-κN(1))ethylidene]nicotinohydrazide-κ(2)N',O}manganese(II), [MnCl2(C12H11N5O)], (I), bis{N'-[1-(pyrazin-2-yl-κN(1))ethylidene]nicotinohydrazidato-κ(2)N',O]manganese(II), [Mn(C12H10N5O)2], (II), and poly[[(acetato-κ(2)O,O'){μ3-N'-[1-(pyrazin-2-yl-κ(2)N(1):N(4))ethylidene]nicotinohydrazidato-κ(3)N',O:N(1)}cadmium(II)] chloroform disolvate], {[Cd(C12H10N5O)(CH3COO)]·2CHCl3}n, (III), respectively. Complex (I) has a mononuclear structure, the Mn(II) centre adopting a distorted square-pyramidal coordination. Complex (II) also has a mononuclear structure, with the Mn(II) centre occupying a special position (C2 symmetry) and adopting a distorted octahedral coordination environment, which is defined by two O atoms and four N atoms from two N'-[1-(pyrazin-2-yl)ethylidene]nicotinohydrazidate (L(-)) ligands related via a crystallographic twofold axis. Complex (III) features a unique three-dimensional network with rectangular channels, and the L(-) ligand also serves as a counter-anion. The coordination geometry of the Cd(II) centre is pentagonal bipyramidal. This study demonstrates that HL, which can act as either a neutral or a mono-anionic ligand, is useful in the construction of interesting metal-organic compounds.
