Bis[μ-N′-(adamantan-1-ylcarbonyl)-2-oxidobenzohydrazidato(3−)]tetrapyridinetrinickel(II) dimethylformamide monosolvate monohydrate

Abstract

In the title trinuclear NiII compound, [Ni3(C18H19N2O3)2(C5H5N)4]·C3H7NO·H2O, three NiII cations are bridged by two N′-(adamantan-1-ylcarbon­yl)-2-oxidobenzohydrazidate trianions. The central NiII cation has a distorted octa­hedral N4O2 coordination environment where a reverse torsion occurs between the two bridging ligands, whereas the two NiII cations on the sides each adopt an N2O2 square-planar coordination. Weak intra­molecular C—H⋯O and C—H⋯N inter­actions help to stabilize the mol­ecular structure. In the crystal, the lattice water mol­ecule links with the NiII complex and dimethyl­formamide solvent mol­ecule via O—H⋯O hydrogen bonding.

Synthesis, structure, and magnetism of a novel series of trinuclear nickel(ii) clusters

“…25–35 For nickel( ii ) complexes with H 3 fshz and its derivatives ligands, trinuclear clusters are more common from the previous reports, but most of them are unstable in air and can lose their solvent molecules, resulting in efflorescence. 32,33 The design and synthesis of stable nickel( ii ) complexes using H 3 fshz and exploring their magnetic properties remain a significant challenge. Herein, we report the synthesis, crystal structure, and magnetic properties of five novel linear trinuclear Ni( ii ) complexes based on the H 3 fshz ligand: Ni 3 (fshz) 2 (L) 4 · n (sol) (H 3 fshz = N -formylsalicylhydrazide, L = pyridine, n = 0, 1 ; L = 4-methylpyridine, n = 1, sol = CH 3 CN, 2 ; L = 4-ethylpyridine, n = 2, sol = CH 3 OH, 3 ; L = 4-vinylpyridine, n = 1, sol = CH 3 OH, 4 ; L = 2,6-pyridinedimethanol, n = 2, sol = CH 3 OH, 5 ).…”

“…[21][22][23][24] In recent decades, N-formylsalicylhydrazide (H 3fshz) and its derivatives, which have multiple O-and N-coordination sites, a great conjugated system, and rich hydrogen-bonded donors and accepters, have been used to design polynuclear complexes with different metal ions, such as Ga(III), Fe(III), Mn(III), Cu(II), Ni(II), and Zn(II).

“…Recently, much attention has been paid to multinuclear complexes, because of their magnetic properties and theoretical significance (Wei et al, 2012;Pradeep & Leroy, 2007;Moon et al, 2006;Lin et al, 2001). Thiosemicarbazide derivatives contain an N-N segment which can bridge two metal atoms, enabling them to form multinuclear complexes.…”
