“…The dihedral angle between the planes is 27.3°. The basal bond distances around the Ni(1) atom are in the range of 2.223-2.053 Å , which are longer than those in the reported six-coordinate nickel(II) complex [20]. The apical bond distances are Ni (1) …”

A new Ni(II) complex, namely [Ni 2 (OAc)L]Á ClO 4 ÁH 2 O, was synthesized by [2 ? 2] cyclo-condensation between 2,6-diformyl-4-methylphenol and N,N-bis(3-aminopropyl)-4-methoxybenzylamine (amba) in the presence of nickel(II) and characterized by spectroscopy, elemental analysis, and X-ray single crystal diffraction. The interactions of the complex with DNA have been measured by spectroscopy and viscosity measurements. Absorption spectroscopic investigation reveals intercalative binding of the Ni(II) complex with DNA, with a binding constant of 2.6 9 10 4 M -1 . Fluorescence spectroscopy shows that the Ni(II) complex can displace ethidium bromide and bind to DNA, with a quenching constant of 7.57 9 10 3 M -1 . The appearance of increased CD bands near 245 and 275 nm gives evidence for effective complex DNA binding. The agarose gel electrophoresis studies show that the complex displays effective DNA cleavage activity in the absence of any external agents.

A dinuclear double end-on azido bridged Ni(II) complex [Ni 2 L 2 (μ-1,1 -N 3 ) 2 (N 3 ) 2 ] (1) with the condensation product of 2-quinolinecarboxaldehyde and trimethylammonium acetohydrazide chloride (Girard's T reagent) (HLCl) has been synthesized and characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction, magnetic measurements and DFT studies. In complex 1 intra-dimer ferromagnetic coupling between Ni 2+ ions (J = +12.0(2) cm -1 ) and inter-dimer antiferromagnetic interaction (δ = -0.8(3) cm -1 ) were observed. DFT-BS calculations provided explanation of ferromagnetic exchange coupling in complex 1.

Three new phenolate oxygen bridged transition metal complexes [Zn3(HL1)3(μ3‐CH3O)]·(ClO4)2(H2O)3 (1), [Ni2(HL1)2(μ1,1‐N3)(o‐vanillin)]·H2O (2), [Ni3(HL2)2(PhCOO)2(PhCOOH)2(EtOH)2] (3) have been synthesized by metal ions and potentially multidentate Schiff base ligands (H2L1 = 2‐((1‐hydroxy‐2‐methylpropan‐2‐ylimino) methyl)‐6‐methoxyphenol; H3L2 = (E)‐1‐((2‐hydroxy‐3‐methoxy‐benzylidene)amino)ethane‐1,2‐diol). All the three complexes 1, 2, and 3 have been characterized by elemental analysis, FT‐IR spectroscopy, and single‐crystal X‐ray diffraction studies. Crystal structures reveal that complex 1 is a trinuclear incomplete cubane‐like zinc cluster whereas complex 2 is a dinuclear nickel complex bridged by azide, and compound 3 is a trinuclear nickel complex. The luminescent property for complex 1 and magnetic behaviors for complexes 2 and 3 have been investigated.
