Ligand mediated structural diversity of copper(II)-azido moiety: Synthesis, structure and magnetic study

Abstract Two copper azido complexes [Cu4(L1)4(µ1,1-N3)3(N3)] (1) and [{Cu2(L2)(N-benzylen)(µ1,1-N3)3(µ1,1,3-N3(N3)]n (2) have been synthesized by the reaction of aqueous solution of sodium azide to a methanolic solution of copper perchlorate hexahydrate and corresponding Schiff-base ligands. Schiff bases HL1 and HL2 act as blocking coligands are derived from the 1:1 condensation of N-benzyl ethylenediamine with Salicyldehyde and 2-hydroxy-5-chloroacetophenone respectively (N-benzylen is the N-benzyl ethylenediamine). These two complexes are characterized by the elemental analysis, FT-IR, single crystal X-ray diffraction, powder XRD and also TGA. Single crystal X-ray structural study reveals…

Double azido-bridged and mixed-bridged binuclear copper(II) and nickel(II) compounds with N,N,O-donor Schiff bases: Synthesis, structure, magnetic and DFT study

Abstract Two dinuclear complexes μ1,1-azido bridged [Cu(L1)(N3)]2 (1) and μ-phenoxo, μ1,1-azido bridged [Ni2(L2)2(μ1,1-N3)(N3) H2O] (2) bearing HL1 and HL2 as a blocking co-ligands produced by the 1:1 condensation of N-benzyl ethylenediamine with ortho-hydroxy acetophenone and N-methyl propanediamine with 3-methoxy salicylaldehyde respectively, have been synthesized and successfully characterized by elemental analyses, IR and electronic spectroscopy, single-crystal X-ray diffraction, variable temperature magnetic study and DFT studies. X-ray crystal structures of 1 reveal that the Cu(II) ion displays a five-coordinate square pyramidal coordination with a centro-symmetric μ1,1-azido bridging…

Unexplored analytics of some novel 3d–4f heterometallic Schiff base complexes

Three heterometallic Schiff-base complexes of Cu having Pr, Nd and Sm as the heteroatoms have been synthesized. The compounds have also been characterized by their IR spectra and CHN analysis. The single crystal structures of these compounds have been studied from the X-ray crystallographic data. To the best of our knowledge the article describes the possibility of application of these compounds in the field of species dependent anion sensing for the first time. Amongst a number of anionic species, certain sulphur species were found to have greater reactivity towards a Schiff-base complex as they can incur probable changes in the molecular complexity. The S2O82−and S2O32− species could modi…

Quantitative estimation of the antiferromagnetic interaction between Cu(II) and Sm(III) in two dimensional heterometallic coordination polymer with isonicotinic acid as tectons

Abstract The syntheses, structure and magnetic property of a novel two dimensional 3d–4f coordination polymer 2∞[CuSmL(NO3)2(IN)], 1 (L2−  = N, N′- propylenedi (3-ehoxysalicylideneiminato), the dianion of the Schiff base obtained from the 2:1 condensation of 3-ethoxysalicylaldehyde with 1,3-propanediamine, IN− = the isonicotinate ion) has been reported. The heterobinuclear units are connected through exo-bidentate ligands IN−, leading to an extended 2D structure. A fit of the magnetic susceptibility data yields gCu = 2.109, gSm = 0.476, JCuSm = − 0.893 cm− 1, θ = − 3.37 K, and TIP = 0.001257 emu K mol− 1 with a good discrepancy factor of Rχ = 4.4 × 10− 5. This is the first quantitative esti…
