(a,b,c) X-ray crystal structures of Yb-sq viewed along the a axis (a) and b axis (b). Top views of the coordination spheres around Yb1 and Yb2 (c). The thermal ellipsoids are drawn at the 50% probability level. Color codes: Yb, green; C, grey; O, red; H, white. The symmetry operation codes for i, ii, and iii are (x, -1+y, z), (x, 1-y, -1/2+z), and (x, 1-y, 1/2+z), respectively. (Dalton Trans. 2023,52,8873)
(a) Temperature dependence of kaimT for Ln-sq (Ln = 63Eu to 70Yb) on the formula [Ln2(sq)3(H2O)8] basis, measured at 500 Oe. The sample was fixed with eicosane for removing the field-align effect due to torqueing. (b) M–H curves for Ln-sq, measured at 1.8 K without eicosane (1 T corresponds to 104 Oe). (Dalton Trans. 2023, 52, 8873)
(a) AC magnetic susceptibilities as a function of frequency for Tm-sq at an applied DC field of 0.18 T. (b) The Cole–Cole plot with the data given from (a). Solid lines in (a) and (b) are drawn as calculation according to the generalized Debye model. Only selected data are shown for the sake of clarity. (c) The Arrhenius plot for Tm-sq. The data were given from (a). Solid lines are drawn as calculation. (Dalton Trans. 2023, 52, 8873)
(a) AC magnetic susceptibilities as a function of frequency for Yb-sq at an applied DC field of 0.04 T. (b) The Cole–Cole plot with the data given from (a). Solid lines in (a) and (b) are drawn as calculation according to the generalized Debye model. Only selected data are shown for the sake of clarity. (c) The Arrhenius plot for Yb-sq. The data were given from (a). Solid lines are drawn as calculation. (Dalton Trans. 2023, 52, 8873)
The coordination environment of copper ions in MOF 1 (a) and two different Cu dimer system connected with two kinds of phosphate groups (b). Atomic numbering is also shown and ellipsoids are drawn at the 30% probability level for non-hydrogen atoms. Symmetry codes for i, ii, and iii are (x, -1+y, z), (-1/2+x, 1/2-y, z), and (-1/2+x, 1/2-y, z), respectively. (Bull. Chem. Soc. Jpn. 2023, 96, 1129)
The coordination environment of copper ions in MOF 2 (a) and Cu tetramer system (b). Atomic numbering is also shown and ellipsoids are drawn at the 30% probability level for nonhydrogen atoms. Only a major configuration is drawn for the disordered portion, marked with A in the atomic numbering. Symmetry codes for i, ii, iii, iv, and v are (x, 1 + y, z), (1 + x, y, z), (1 - x, 2 - y, z), (2 - x, 1 - y, 1 - z), and (2 - x, 2 - y, 2 - z), respectively. (Bull. Chem. Soc. Jpn. 2023, 96, 1129)
The temperature dependence of kaimT and kaim-1 for MOF 1 (a) and MOF 2 (b) on the formula basis. The plots were drawn after the temperature-independent paramagnetic term was subtracted. (Bull. Chem. Soc. Jpn. 2023, 96, 1129)
Crystal structure of [Y(hfac)3(H2O)2(TF2PBN)]·[Y(hfac)3(H2O)2]1.1 with thermal ellipsoids at the 50% probability level. Major conformations are drawn for disordered CF3 groups at C17 (occupancy 0.640(4)), C26 (0.770(5)), and C31 (0.68(2)). Dotted lines stand for H bonds, as denoted between the oxygen atoms. Selected atomic numbering is also shown. Atomic color codes: C, gray; H, turquoise; N, blue; O, red; F, yellow; Y, green. (Molecules 2024, 29, 70)
