چکیده
The mononuclear title complex, [Fe(CF3O3S)(C5H7O2)2(C4H8O)] or [Fe(acac)2(OTf)(THF)] (acac = acetyl-acetonate; OTf = tri-fluoro-methane-sulfon-ate; THF = tetrahydrofuran), (I), consists of one six-coordinate Fe(3+) atom in a slightly distorted octa-hedral environment [Fe-O bond-length range = 1.9517 (11)-2.0781 (11) Å]. The triflate ligand was found to be disordered over two sets of sites, with a site-occupancy ratio of 0.622 (16):0.378 (16). Weak inter-molecular C-H⋯O and C-H⋯F hydrogen-bonding inter-actions generate a two-dimensional supra-molecular structure lying parallel to (100). This is only the second crystal structure reported of a mononuclear bis-(acetyl-acetonato)iron(III) complex.

The title chain polymer compound, [GaLi(2)Br(C(3)H(9)OSi)(4)(C(4)H(8)O)(2)](n), was obtained in the reaction of GaBr(3) with Me(3)SiOLi in toluene/tetra-hydro-furan. The Ga(III) atom, located on a twofold rotation axis, is coordinated by four trimethyl-silanolate ligands and has a distorted tetra-hedral geometry. The Li(I) atom is four coordinated by one bridging Br atom located on an inversion...

In the title complex, [Mn(C(15)H(11)N(3)O(5))(C(5)H(7)O(2))(H(2)O)], the Mn(III) ion has a distorted octa-hedral coordination geometry. It is coordinated by a phen-oxy O atom, a hydrazine N atom and a carbonyl O atom of the 2-(2-nitro-phen-oxy)-N'-(2-oxidobenzyl-idene-κO)acetohydrazidate dianion, by two O atoms of the acetyl-acetonate anion and by the O atom of a coordinated water mol-ecule.

In the title monomeric rare earth complex, [LiNd(C(19)H(40)N(3)Si(2))(2)Cl(2)(C(4)H(8)O)(2)], the [(Me(3)Si)(2)NC(NCy)(2)](2)Nd(+) (Me is methyl, Cy is cyclo-hex-yl) and Li(THF)(2) (+) units (THF is tetra-hydro-furan) are connected by two bridging Cl atoms. The Nd(3+) ion is coordinated by two guanidinate ligands and two Cl atoms, forming a distorted chelating octa-hedral geometry. The Li(+) io...

In the title complex, [Mn(C(5)H(7)O(2))(2)(NCS)(CH(4)O)], the Mn(III) atom has a slightly distorted octa-hedral coordination formed by five O atoms and one N atom. The equatorial positions are occupied by four O atoms of two acetyl-acetonate ligands, while the axial positions are occupied by the N atom of the thio-cyanate anion and the O atom of the methanol mol-ecule. In the crystal structure,...

The title co-crystal, [Eu(NCS)3(C18H15OP)3][Eu(NCS)2(NO3)(C18H15OP)3], contains two distinct neutral complexes. Each complex has threefold symmetry about its central Eu(3+) ion. As a result, the nitrate-containing mol-ecule contains disorder of its bidentate nitrate and two N-bound thio-cyanate anions, while the [Eu(NCS)3(OPPh3)3] complex is fully ordered. There is a weak π-π stacking inter-act...
