A nanotubular 3D heterometallic zeolitic polymer, {[Yb(PDA)3Mn1.5(H2O)3].1.5H2O}n (2), was designed and synthesized by simply tuning the amount of coordinated water on the Mn ion in the molecular ladder polymer {[Yb(PDA)3Mn1.5(H2O)6].6H2O}n (1). 1 and 2 were structurally and magnetically characterized. The water molecules capsulated within the nanotube were(More)
Reaction of Dy(hfac)(3)·2H(2)O (hfac = hexafluoroacetyl acetonate) with 2-(2-hydroxyphenyl)nitronyl nitroxide (NITPhOH) and 2-(5-bromo-2-hydroxyphenyl)nitronyl nitroxide (NIT5BrPhOH) yielded [Dy(2)(hfac)(4)(NITPhO)(2)] 1 and [Dy(2)(hfac)(4)(NIT5BrPhO)(2)] 2, respectively. These compounds are phenoxo-O bridged binuclear complexes with the radical unit of a(More)
A new nitronyl nitroxide bridged one-dimensional lanthanide complex [Tb(3)(hfac)(9)(NIT-2thien)(3)](n) (1) (NIT-2thien = 2-(2'-thienyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide) has been successfully prepared. Single crystal X-ray crystallographic analysis reveals that complex 1 consists of linear chains built up by Tb(hfac)(3) units bridged by(More)
This paper reports the synthesis, crystal structures, and magnetic properties of a series of mixed-valence polynuclear manganese complexes bridged by a dianionic 1,2,4-triazole-based ligand L(2-) (H(2)L = 3-(2-phenol)-5-(pyridin-2-yl)-1,2,4-triazole). Complexes 1 to 3 show a similar binuclear structure, with the central core of [Mn(II)Mn(III)(L)(2)] and(More)
Four new copper(II) complexes, [Cu(1,4-tpbd)Br(2)] (), [Cu(2)(1,4-tpbd)(H(2)O)(4)](ClO(4))(4) (), [Cu(2)(1,4-tpbd)(1,10-phen)(2)(DMF)(2)](ClO(4))(4) () and [Cu(2)(1,4-tpbd)(2,2'-bpy)(2)(ClO(4))(2)](ClO(4))(2) (), [1,4-tpbd = N,N,N',N'-tetrakis(2-pyridylmethyl)benzene-1,4-diamine], have been synthesized to serve as artificial nucleases. Single crystal X-ray(More)
A novel approach for the preparation of hetero-tri-spin magnetic compounds is described. It consists in using preformed metal-nitronyl nitroxide complexes as metallo-ligands in an assembling process involving an additional metal centre. This is illustrated by two unprecedented radical-Cu-Ln chain compounds (Ln = Gd(3+), Tb(3+)).
Two unprecedented 2D entangled layers of warp-and-woof threads interwoven by left- and right-handed helical chains, {[Mn(salen)Au(CN)2]4(H2O)}n (salen = N,N'-ethylenebis(salicylideneaminato)) and {Mn(acacen)Ag(CN)2}n (acacen = N,N'-ethylenebis(acetylacetonylideneiminate)) 2, have been synthesized and characterized.
The dinuclear copper(II) complex [Cu2(mu(1,1)-N3)2(im-2py)2(N3)2] [im-2py = 2-(2-pyridyl)-4,4,5,5-tetramethylimidazolinyl-1-oxy] has been prepared and structurally characterized. The crystal structure consists of a dinuclear unit in which the Cu(II) ions are bridged by two azido ions in a end-on asymmetric fashion and the imino nitroxide radicals are(More)
A new Fe(III)(6) cluster, [Fe(3)L(2)(ida)(mu-OH)(3)(mu-O)](2).4ClO(4).2CH(3)OH.8H(2)O (1) (where L = N-methyl-N,N-bis(2-pyridylmethyl)amine; H(2)ida = iminodiacetic acid), has been synthesized and magnetic properties are shown. The asymmetric unit of 1 contains a triangular [Fe(3)L(2)(ida)(mu-OH)(3)(mu-O)](2+) unit and two such trinuclear units are further(More)
