Syntheses, studies and crystal structures of coordination polymers and dinuclear complexes of mercury(II) halides and thiocyanate with a symmetrical Schiff base ligand

Mixed ligand complexes of copper(II), cobalt(II), nickel(II) and zinc(II) with thiocyanate and pyrazole based tetradentate ligand: Syntheses, characterizations and structures

“…Various types of tripodal ligands with aromatic or aliphatic amine and their metal complexes have been synthesized and characterized [18][19][20][21]. Thiocyanate is an ambidentate pseudohalide and can coordinate with metal ions as terminal or bridging ligand to give monomeric, dimeric and polymeric complexes [22][23][24][25][26][27][28][29][30][31]. It has great potential in building up of coordination networks of varied dimensionalities when it acts as bridging ligand [32][33][34].…”

Synthesis, crystal structures and vapor adsorption properties of mercury(II) coordination polymers derived from two dipyridylamide ligands

“…The ClÀ HgÀ Cl and HgÀ ClÀ Hg bond angles of the Hg 2 Cl 2 parallelograms are 81.7 and 98.3°, respectively, consistent with those of similar complexes. [31] The HgÀ N bond length are 2.623(10) and 2.628(10) Å, which are longer than those HgÀ N contacts in the related complexes. [32,33] The Hg•••Hg distances bridged by ligand L 2 and bridged by the Cl atoms are 20.839 and 4.135 Å, respectively.…”

Syntheses, Characterization, and Crystal Structures of a Dinuclear Complex and Coordination Polymer of Mercury(II) with Schiff Base Ligands containing N3 and N4 Donors

“…In the molecular structures of the complex each central Hg [14,24,25] It is interesting that the 1D coordination polymer in compound 3 in Ref. [14] was changed to compound 1 by replacing of the hydrogen atom with a methyl group in the ligand L. The main difference of the two structures is due to the coordination mode of I -. It seems that the steric effects of methyl groups in the ligand L have an effect on the kind of coordination mode of I -atoms in mercury(II) coordination polymers.…”

“…[14] Herein, the classical tetradentate Schiff base, N,NЈ-bis(phenyl(pyridin-2-yl)methylene)propane-1,2-diamine (L) and the tridentate Schiff base amine, N-(phenyl(pyridin-2-yl)methylene)propane-1,2-diamine (LЈ) (Scheme 1) were chosen to isolate mercury(II) iodide compounds with different arrangements and molecular properties. …”
