چکیده
In the title compound, [Tm(C6H5Se)3(C4H8O)3], the Tm(III) atom lies on a threefold rotation axis and is coordinated by three phenyl-seleno-late ligands and three tetra-hydro-furan ligands leading to a distorted fac-octa-hedral coordination environment. The Tm-Se and Tm-O bond lengths are 2.7692 (17) and 2.345 (10) Å, respectively, and the bond angles are 91.32 (6)° for Se-Tm-Se, 92.6 (2) and 94.4 (2)° for Se-Tm-O, and 81.2 (3)° for O-Tm-O. In the crystal, the discrete complexes are linked by van der Waals inter-actions only. The crystal was refined as a non-merohedral twin (ratio = 0.65:0.35).

In the mononuclear title compound, [Tb(C(13)H(9)OS(3))(3)(C(4)H(8)O)(3)]·C(4)H(8)O, the lanthanide cation is located on a threefold rotation axis and is surrounded by electron-rich ligands in an approximately octa-hedral geometry. One of the thienyl groups and the bound THF are disordered with 0.5:0.5 occupancy. The free THF is disordered around the threefold axis.

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...

In the title Ho(III)-erythritol complex, [Ho(NO3)3(C4H10O4)(C2H5OH)], the Ho(III) cation is chelated by a tridentate erythritol ligand and three bidentate nitrate anions. An ethanol mol-ecule further coordinates the Ho(III) cation, completing the irregular O10 coordination geometry. In the crystal, an extensive O-H⋯O hydrogen-bond network links the mol-ecules into a three-dimensional supra-mole...

In the tetra-hydro-furan solvate of the title salt, C12H36N6P3 (+)·C24H20B(-)·C4H8O, the cation features short P-P bond lengths [2.1111 (11) and 2.1364 (10) Å] and a distinctly bent P-P-P angle [104.67 (4)°] that confirm that the mol-ecule is not allene-like. In the crystal, the solvent mol-ecule is linked to the cation via a weak C-H⋯O hydrogen bond.
