“…Employing this ligand, we have also reported the coordination‐cum‐binding events of biologically relevant monosaccharides such as D‐glucose, D‐xylose and D‐mannose with new mononuclear iron(III) and zinc(II) complexes in aqueous solution . Similar carboxyamine‐based tridentate N , N , O ligands which easily coordinate to copper(II), cobalt(II) and nickel(II) ions to form one dimensional coordination polymers have been reported in the literature . It is noteworthy to mention that the (2‐pyridyl)alkylamine‐appended carboxylate‐based ligands are well‐utilized to prepare the coordination polymers of manganese(II), cobalt(II), nickel(II), copper(II), zinc(II) and lanthanum(III) ions which have exhibited interesting magnetic properties .…”

A carboxyamine functionalized tridentate ligand in combination with three different carboxylate bridging groups (RCO 2 À ; R = CH 3 , C 2 H 5 and CF 3 ) has been utilized to prepare tetra-and pentanuclear nickel(II) complexes, [Ni 4 (CC 2 H 5 ) 2 (CH 3 OH) 2 ] (2) and [Ni 5 (L) 4 (μ 3 -OH) 2 (μ 1,3 -O 2 CCF 3 ) 2 ]Br 2 ⋅3H 2 O (3) (HL = 3-[(2-pyridylmethyl)-amino]-propionic acid). The complexes have been characterized using several techniques such as elemental analysis, solution electrical conductivity, FTIR and UV-Vis spectroscopy, and low temperature magnetic measurements. While complex 1 and 3 were further characterized using single crystal X-ray diffraction, molecular structure of complex 2 has been optimized using DFT calculation. Whereas the acetate/propionate groups deliver Ni 4 cluster, the trifluoroacetate group provides Ni 5 assembly. Molecular structures of complexes 1 and 2 comprise a central [Ni 4 O 6 ] core that could be described as a distorted face-shared dicubane with two missing vertices. On the other hand, the [Ni 5 (μ 3 -OH) 2 (μ 1,3 -O 2 CCF 3 ) 2 ] 6 + structural core of complex 3 contains five coplanar nickel(II) ions in a rectangular organization. Variable-temperature magnetic susceptibility studies reveal the interesting magnetic properties of complexes 1 and 3. While complex 1 shows both ferro-and antiferromagnetic interactions with J 1 = À 1.10 cm À 1 , J 2 = + 2.40 cm À 1 and J 3 = À 0.65 cm À 1 , complex 3 exhibits only ferromagnetic interactions with J 1 = + 2.0 cm À 1 and J 2 = + 1.0 cm À 1 .

Two new Schiff base copper(II) complexes, [CuL 1 (tmen)] (1) and [Cu 2 L 2 2 (tmen)] (2) {where, H 2 L 1 = N-(salicylidene)-L-valine, H 2 L 2 = N-(3,5-dichlorosalicylidene)-L-valine and tmen = N,N,N ,Ntetramethylethylene-1,2-diamine} have been synthesized and characterized by molar conductance, elemental analyses, VSM-RT, UV-Vis, FTIR, EPR, and CD spectra. Both the complexes were structurally characterized by single crystal XRD. The crystal structure of complex 1 displays a distorted square pyramidal geometry in which Schiff base is coordinated to the Cu(II) ion via ONO-donor in the axial mode, whereas, the chelating diamine displays axial and equatorial mode of binding via NN-donor atoms. The crystal structure of the complex 2 reveals a syn-anti mode of carboxylate bridged dinuclear complex, in which, the coordination geometry around Cu(1) is square pyramid and distorted square planar around Cu(2). The target complexes were screened for in vitro antidiabetic activity. Both the complexes showed good inhibitory activity for α-amylase and α-glucosidase.
