Syntheses, structures, and magnetic properties of dicyanamide bridged one-dimensional double chain and discrete dinuclear complexes of manganese(II) derived from 6,7-dimethyl-2,3-di(2-pyridyl)quinoxaline or 2,4,6-tri(2-pyridyl)-1,3,5-triazine

Dichlorido(2,4,6-tri-2-pyridyl-1,3,5-triazine)manganese(II)

“…For the crystal structure of 2,4,6-tri-2-pyridyl-1,3,5-triazine (tptz), see: Drew et al (1998). For the crystal structures of some other Mn(II)-tptz complexes, see: Hsu et al (2006); Majumder et al (2006); Sun et al (2007); Tyagi & Singh (2009); Zhang et al (2008); Zhao et al (2007).…”

“…Since the original structure determination of 2,4,6-tri-2-pyridyl-1,3,5-triazine ligand (Drew et al, 1998), triazine complexes, including Mn(II) derivatives, have attracted considerable interest over the years (Hsu et al, 2006;Majumder et al, 2006;Sun et al, 2007;Tyagi & Singh, 2009;Zhang et al, 2008;Zhao et al, 2007). In the title complex, [MnCl 2 (C 18 H 12 N 6 )], the Mn II ion is five-coordinated in an approximately square-pyramidal geometry by three N atoms of the tridentate 2,4,6-tri-2-pyridyl-1,3,5-triazine ligand and two Cl atoms ( Fig.…”

X-ray Structure Analyses and Biological Evaluations of a New Cd(II) Complex with S-Triazine Based Ligand

“…s-Triazine pincer ligands have a weak ligand field, which supports the synthesis of interesting high-spin complexes for different magnetic applications [32,33]. Additionally, this class of ligands is characterized by the presence of a symmetric triazine core, which is an important feature in crystal engineering [34][35][36][37][38][39][40][41][42][43][44]. On continuation of our interest into the structural aspects and biological applications of bis-pyrazolo-s-triazine complexes [45][46][47][48][49][50][51], the present work aims to synthesize a new Cd(II) complex of the 2,4-bis(3,5-dimethyl-1H-pyrazol-1-yl)-6-methoxy-1,3,5-triazine (BPMT, Figure 1) ligand, shedding the light on its molecular and supramolecular characteristics.…”

Synthesis, Crystal Structure and Magnetic Properties of a Dinuclear Mn(II) Complex with two syn–Anti Bridging Carboxylate Groups

“…There has been considerable research interest in the magnetic behaviour of polynuclear manganese complexes in the recent years. [1][2][3][4][5] The increasing interest in this field is justified not only by the development of new precursors for molecule-based magnetic materials, [6][7][8][9][10][11][12][13][14] but also by the intellectual challenge of elucidating the fundamental relationship between structures and magnetic properties. [15][16][17][18][19][20][21][22] One of the points to be seriously considered for the preparation of these magnetic solids is to choose appropriate bridging ligands that can transmit magnetic interactions and bind several metal centres through various bonding modes and also to introduce some chelating or linear ditopic ancillary ligands to tune the composition and structure.…”
