Tetrahedra, Super‐Tetrahedra, Bipyramids, Boxes and More: Polymetallic Clusters of Benzotriazole

Abstract

The syntheses, structures and magnetic properties of a host of polymetallic 3d transition-metal clusters made with the pro-ligand benzotriazole (BtaH) and its analogues are reported. These range from a family of tetradecametallic clusters with spin ground states as large as S Ϸ 25, to decametal-

Benzotriazolate cage complexes of tin(ii) and lithium: halide-influenced serendipitous assembly

“…3, 4 A common coordination mode of [bta] -involves the ligand bridging between three metals, illustrated schematically as [(bta)M 3 ] (1). The natural orientation of the lone pairs on the vicinal nitrogen donors in [bta] -provides an important structuredirecting influence, which allows access to a range of structurally diverse polymetallic transition metal cage complexes.…”

“…We now report that the general principles of the one-pot method developed for 2 can be extended to the synthesis of bimetallic [bta] -complexes of tin(II) and lithium by using SnX 2 with X = Cl or Br in reactions with [Li(hmds)] and (bta)H. These reactions produced the isostructural hexadecametallic cages [(hmds) 8 4 ]·(thf), the structure of which contains a cyclic ladder of lithium benzotriazolate and a rare example of the saw-horse-shaped tetraiodostannate(II) dianion.…”

catena-Poly[copper(II)-μ-aqua-di-μ-benzotriazole]

“…Despite of the extensive use of Bta and its derivatives as corrosion inhibitors for copper, zinc, silver and their alloys (Collison et al, 2006;Okeefe & Steel, 2000), only a few compounds have been characterized by X-ray diffraction (Himes et al, 1981;Hu et al, 2005;Jones et al, 2005;Li et al, 2002;Rajeswarana et al, 2006). Most of the structures involve inorganic anions such as Zn(Bta) 4 (H 2 O) 2 (ClO 4 ) 2 and Cu(Bta) 4 (H 2 O) 2 (ClO 4 ) 2 (Himes et al, 1981;Jones et al, 2005;Li et al, 2002).…”

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

“…[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. 49 We therefore sought to explore the potential of semi-rigid ligands in the field of CPs, in conjunction with the coordination capabilities of benzotriazole.…”
