Metal-radical coordination complexes of thiazyl and selenazyl ligands

“…Work by Murray, Tong, Winpenny and others has definitively established that, for Dy and other Ln single molecule magnets (SMMs), the nature of the ligands and the ligand sphere geometry can dramatically alter the SMM properties [83][84][85]. The implication for the [Dy(hfac) 3 boaDTDA] 2 supramolecular pair is that the magnetization dynamics of the two Dy ions may be different from one another. Measured under zero dc field, the [Dy(hfac) 3 boaDTDA] 2 supramolecular pair exhibits slow magnetization dynamics consistent with SMM behavior.…”

“…The Mn II and Cu II complexes both form pancake bonds in the solid state, however the dimerization motifs for the two are different. Whereas the DTDA heterocycles of the [Mn(hfac) 2 (pyDTDA)] 2 pair interact to form a cis-cofacial pancake bond, the Cu II complex dimerizes in a twisted-cofacial motif, [Cu(hfac) 2 (pyDTDA)] 2 (Fig. 8).…”

“…As observed with thiazyl radical cations (vide supra), ionic complexes of 125TDA radical anions that incorporate a metal-containing counterion may also exhibit structural features consistent with coordination between the thiazyl radical and the metal. Crystal structures of a solvated and an unsolvated ionic complex of the [1,2,5]thiadiazolo [3,4- [111]. In the unsolvated species, the radical anion acts as a bridging ligand, forming a onedimensional -metal-radical-coordination polymer (Fig.…”

“…The 6,7-dimethyl-1,4-dioxo-naphtho [2,3-d] [1,2,3]dithiazolyl ligand (67Me 2 pDTANQ) is a dimethyl derivative of 1,2,3-dithiazolyl-p-naphthoquinone [99], designed to be a better σ-donor and to be more soluble than the parent species. There are two possible coordination sites, a bidentate N,O-chelation pocket and monodentate Ocoordination site on the opposite side of the molecule.…”

Mass and infrared spectra of some S4N4 complexes of group VIII metals

“…Following this, it was quickly established that monomeric M(NS), complexes could be synthesized by three_ main routes: heating anhydrous MC1, (M = Ni, Co, Pd) with S4N4 in alcohols (2); reaction of metal carbonyls (e.g., Co2(CO), (3) and Fe(CO), (4)) with S4N4; shaking finely divided metal powders (Ni, Co, Pd) with S2N2 in tetrahydrofuran (5). The analogous platinum derivative, Pt(NS),, was prepared by the reaction of H2PtC16 with S4N4 in dimethylformamide-H20 (6).…”
