“…Similar results were also reported for Cu(II) complex with reduced Schiff base derived from N-(2-hydroxybenzaldehyde) and L-methionine with 1-D coordination polymers with the binuclear copper fragments as building blocks [25]. There are other reports on Cu(II) complexes to form 1-D polymeric chain structures [33][34][35][36]. For example, the hexanuclear unit is formed by assembly of two tetranuclear subunits via two copper ions coordinating simultaneously to two N,N 0 -2,6-pyridinedicarboxyl)-disalicylhydrazide ligands, and the 1-D chain structure of the compound is constructed by connection of hexanuclear units via bridging phenolic oxygens of ligands [34].…”

New zinc(II) and copper(II) complexes with a reduced Schiff-base ligand derived from D,L-selenomethionine and salicylaldehyde have been synthesized and characterized by elemental analysis, magnetic susceptibility, IR, and NMR measurements. The single-crystal X-ray structure of the Cu(II) complex reveals that this complex is a carboxylate-bridged dimer of dinuclear copper(II) subunits and all metal centers are five-coordinate with O 4 N donor sets in distorted square-pyramidal geometries. The Cu(II) complex consists of a 1-D coordination polymer.

“…N -Acylsalicylhydrazides are ideal ligands for the synthesis of novel polynuclear metal complexes due to their multiple N,O atoms with strong coordination ability, abundant hydrogen-bond donors, acceptors, and large conjugation systems. , In addition, the N -acylsalicylhydrazide metal macrocyclic compounds are no longer limited to the trivalent metal ions as monosalicylhydrazide ligands. Moreover, in their macrocyclic compounds, there are more abundant cyclization modes; besides [M–N–N–M] repeat units, they can also be used to form rings …”

Caprylic hydrazide ligands are ideal ligands for the synthesis of novel polynuclear metal complexes, because they contain many N,O coordination atoms with a strong coordination ability, abundant hydrogen-bond donors, acceptors, and large conjugation systems. Here, we successfully obtained one d o d e c a n u c l e a r c o b a l t n a n o c l u s t e r [Co II 8 Co III 4 (L1) 4 (Py) 12 (CH 3 OH) 4 (CH 3 COO) 4 ]•(CH 3 OH) 13 (1) and one octadecanuclear cobalt nanocluster [Co II 18 (L2) 6 (Py) 48 ]•(DMF) 5 •(CH 3 OH) 8 ( 2) by using H 6 L1 and H 6 L2 ligands, respectively (Py = pyridine; DMF = dimethylformamide). The cyclic cobalt nanocluster 1 can be regarded as two pentanuclear cobalt units (Co 5 (N−N) 4 ) connected by two cobalt ions, and it is a mixed-valent Co nanocluster. Every H 6 L1 ligand contains 10 coordination atoms, each of which coordinates with the Co ions. And every two H 6 L1 ligands form a structure similar to a handshake. The abnormal cylindrical cobalt nanocluster 2 can be regarded six trinuclear cobalt units Co 3 (N−N) 2 connected by one L2 6− ligand, and every L2 6− ligand splits the structure on both sides, with a twisted cyclohexane in the middle. AC magnetic susceptibilities show that nanocluster 1 exhibits no frequencydependent behavior, but nanocluster 2 shows an obviously single-molecule magnetic behavior, and the relaxation process of the energy barrier is 20.4 K.

The reactions of the diacylhydrazine ligands N,N 0 -bisalicyl-2,6-pyridine dicarbohydrazide (H 6 sphz) and6-pyridine dicarbohydrazide (H 6 msphz) with various 3d metal salts, afforded a series of coordination clusters, namely, [Mn III 2 Mn II (sphz)(acac) 2 (CH 3 OH) 4 ] (1, acac À ¼ acetylacetone anions), [Ni II 3 (msphz)(Py) 4 ] (2, Py ¼ pyridine), [Cu II 6 (sphz) 2 (Py) 4 ] (3) and [Cu II 6 (msphz) 2 (Py) 4 ]$2DMF$2H 2 O (4). Cluster1 and 2 are single ligand assembled quasi-linear trinuclear structures. Both 3 and 4 consist a pair of quasi-linear {Cu 3 } cores, which are linked together by two crossed ligands. The adjacent 3d metal ions in all trinuclear cores of 1-4 are bridged by N-N single bonds of ligands, which convey ferromagnetic (FM) interactions between 3d metal centers of 1, and antiferromagnetic (AFM) interactions between those of 2-4. In particular, the FM interactions and linear arrangement of mixed-valence Mn centers in 1 result in a large spin ground states value (S T ) of 13/2, as well as single-molecule magnet (SMM) behavior of slow relaxation and hysteresis of magnetization.
