Abstract

, 3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclopentadeca-7,13-diene) were synthesized and structurally determined. The structure of 1 has oxamido-bridged trinuclear [Cr III Cu

Syntheses, structures and magnetic properties of μ1,5-dicyanamide bridged di- and polynuclear manganese(II) complexes containing neutral N-donor Schiff bases: Control of coordination number and nuclearity by varying denticity

“…Self-assembly [11] of the metal ion with different organic spacers and suitable bridging units is an efficient approach to prepare such coordination molecules. Pseudohalides like azide, thiocyanate and cyanate [12][13][14][15][16][17] have been extensively used for the isolation of such coordination polymers and polymer-based supramolecular entities. Dicyanamide (dca), a larger pseudohalide molecular ionrod is now under active consideration because of its versatile coordination motifs [18][19][20][21][22][23][24][25] such as l 1,5 -, l 1,3 -, l 1,3,5 -, l 1,1,3,5 -and l 1,1,3,5,5 , exhibiting rich diversity in magnetic behaviours including ferromagnetism, antiferromagnetism and canted-spin antiferromagnetism.…”

A novel 2D oxalate- and dissymmetrical oxamidato-bridged heterometallic CuII–GdIII complex: Synthesis, crystal structure and magnetic properties

“…Along this line, the heterospin systems of macrocyclic oxamides have been extensively investigated [23][24][25]. However, only a few kinds of coordination polymers based on macrocyclic oxamidate compound [Cu(L)] and Ln 3+ have been reported [26][27][28][29].…”

Coordination polymer {[Cd2(NiL)2(Btca)2] · H2O}n of macrocyclic oxamide with benzotriazole-5-carboxylate: Syntheses, crystal structures, and fluorescence properties

“…Recently, some aromatic multicarboxy late as co ligands were chosen to design and construct diverse oxamido bridged heteropolynuclear networks [17][18][19][20]. However, those containing oxamide and het erocyclic carboxylate mix bridged polynuclear com plexes have been made rarely [17][18][19][20][21].…”
