A One-Dimensional Manganese(II) Coordination Polymer Derived from Zerovalent Manganese and 1-Hydroxybenzotriazole − Synthesis, Characterization, Crystal Structure and Magnetic Properties

Abstract

The reaction of zerovalent manganese with 1‐hydroxybenzotriazole, btaOH, and NH4SCN in DMF in the presence of dioxygen allows isolation of the one‐dimensional coordination polymer [Mn3(btaO)2(NCS)4(DMF)8]n (3). X‐ray diffraction analysis reveals that the chain is best described as [Mn2(btaO)2(NCS)2(DMF)6] dimers linked by Mn(NCS)2(DMF)2 bridges. Molar magnetic susceptibility measurements of 3 in the 5−300 K range indicate weak antiferromagnetic coupling between the MnII atoms within the dinuclear subunits of the chain.

The “periodic table” of benzotriazoles: Uranium(VI) complexes

“…Crystallographic data for 1, 2, 3 and 4 · diMebtaH · MeCN have been deposited with the Cambridge Crystallographic Data Centre, 12 Union Road, Cambridge CB2 1EZ, UK; fax + 44 1223 336 033; e-mail: Table S2, thin cyan lines), extended parallel to the [1][2][3][4][5][6][7][8][9][10] crystallographic direction in the crystal structure of complex 2. b) The U2-containing molecules form chains through intermolecular π-π (dark green lines) and "non-classical" H-bonding interactions (C13-H13⋯O6, Table S2, thin cyan lines), extended parallel to the b axis. These chains cross each other at points above and below the 6MebtaH ligands creating the 3D structure shown in c and resulting in stacks of ligands presented in d. Light green, yellow and dark green thick lines indicate the three different types of π-π overlaps in the structure of the complex, shown in e, f and g, respectively, with the corresponding distances and angles between the planes being 3.50 Å and 0°(e), 3.37 Å and 5.5°(f), and 3.44 Å and 0°(g).…”

“…Over the last 30 years or so, we [1][2][3][4][5][6][7][8] and other groups [8][9][10][11][12][13][14][15][16][17] have been exploring the coordination chemistry of benzotriazoles. Research in this area ranges from efforts to model the corrosion inhibition of some metals (particularly Cu and its alloys) by benzotriazoles [18], to the synthesis of benzotriazolato coordination clusters [2,[4][5][6][7]9,11,13,15] and polymers [1,3,12,14,16,17] with esthetically pleasing structures and exciting physical properties. Although the use of this family of ligands has been investigated widely in 3d- [1-11, 13-15,17] and 4f-metal [12,16] chemistry, their employment in the chemistry of 5f-metal ions has completely been ignored.…”

Exploring the Coordination Capabilities of a Family of Flexible Benzotriazole-Based Ligands Using Cobalt(II) Sources

“…The middle ground between these two extremes is to employ semi-rigid ligands with a smaller degree of flexibility, which have also been successfully employed to afford porous networks. [24][25][26][27][28][29][30][31] Benzotriazole and its derivatives have been frequently employed in the construction of CPs and MOFs [32][33][34][35][36][37][38][39][40][41][42][43][44] as well as polynuclear coordination clusters (CCs). [45][46][47][48] Its multi-modal coordination ability, through the 1,2,3-triazole moiety, provides enormous versatility when combined with transition metal ions.…”
