2,6-Bis[(2-hydroxy-3-methoxybenzylidene)hydrazinocarbonyl]pyridine monohydrate

Abstract

In the title compound, C(23)H(19)N(5)O(6).H(2)O, the two components are linked into complex chains by a combination of two independent O-H...O and two independent N-H...O hydrogen bonds. The complex chains are linked into a two-dimensional sheet network via pi-pi stacking interactions and C-H...O hydrogen bonds.

Synthesis and Characterization of Two Discrete Ln10 Nanoscopic Ladder‐Type Cages: Magnetic Studies Reveal a Significant Cryogenic Magnetocaloric Effect and Slow Magnetic Relaxation

“…The ligand (H 4 L ) was synthesized following previously reported procedures23 (see the Supporting Information for details). The synthesis and characterization of other lanthanides ([La 10 ], [Sm 10 ], [Tb 10 ] and [Ho 10 ]) are given in the Supporting Information.…”

Formation of a Magnetically Coupled Neutral [4×4] Square Grid from a 2,6‐Pyridinedicarbaldehyde Bis(hydrazone) Ligand

“…The H 4 L 1 ligand was synthesized by following a previously reported procedure [14] (see the Supporting Information for details). X-ray Crystallography: Data collection of complex 1 was performed at 120 K with a Bruker D8 venture CCD diffractometer by using graphite monochromated Cu-K α (λ = 1.54718 Å) radiation under a cold nitrogen stream.…”

A family of Fe3+based double-stranded helicates showing a magnetocaloric effect, and Rhodamine B dye and DNA binding activities

“…Data collection of the complexes 1, 3 and 4 was performed on a Bruker Smart Apex II CCD diffractometer using graphite monochromated MoKα (λ) (0.71073 Å) radiation and complex 2 on a Bruker D8 venture CCD diffractometer using graphite monochromated Cu-Kα (λ = 1.54718 Å) radiation at 120 K using a cold nitrogen stream. Data reduction and cell refinements were performed with the SAINT program 24 and the absorption correction program SADABS 25 was employed to correct the data for absorption effects. Crystal structures were solved by direct methods and refined with full-matrix leastsquares (SHELXL-14) 25b and the OLEX software 26 with atomic coordinates and anisotropic thermal parameters for all non-hydrogen atoms.…”
