“…The latter value is longer than the sum of ionic radii (Cd 2+ CN7 : 1.03 Å; O 2– : 1.35 Å). Similar values were reported for CdN 4 O 3 in the CTP environment, and as expected, the Cd–O bond to the capping O 2– is longer than to O 2– anions in the trigonal prism. − The Cd–N bonds are between 2.196 and 2.485 Å (Table S8), in agreement with literature values. − The N–Cd–N and O–Cd–O cis angles range from 74.4(4)° to 97.9(4)°, respectively, from 62.96(14)° to 65.78(14)°, and the N–Cd−μ 2 -O angles are 74.2(3)–96.8(3)°. The trans angles cover a wide range as expected by different orientations of the monocapped trigonal prisms (Table S9), but the geometric parameters are not unusual and similar data were reported in the literature. ,, …”

Diffusion-based room temperature syntheses using K8{Ta6O19}·16H2O, d-block metal (M) salts (M = Cu, Zn, or Cd), and the macrocyclic ligand 1,4,8,11-tetraazacyclotetradecane (cyclam) led to crystallization of the three new polyoxotantalates with the composition K4{[Cu(cyclam)]2Ta6O19}·18H2O (I), K4{[Zn(cyclam)]2Ta6O19}·18H2O (II), and {[Cd(cyclam)]4Ta6O19}·19H2O (III). The latter two compounds represent the first polyoxotantalates (POTas) with Zn2+ and Cd2+ centered amine complexes and also the first POTas synthesized using a macrocyclic amine. Compounds I and II are isostructural with two complexes attached to the anionic cluster via Cu–O–Ta respectively Zn–O–Ta bonds. Despite that these two compounds are isostructural, the geometry of the M2+ complexes differs significantly with Cu2+ in a square-pyramidal and Zn2+ in a trigonal-bipyramidal environment. In the structure of III, the Cd2+ cations are in the rare hepta-coordinated monocapped trigonal prismatic geometry covalently linked to the anionic core via Cd–O–Ta bonds. While compounds I and II are quite stable under ambient conditions, III shows a fast loss of crystal water molecules. Temperature-dependent in situ XRD measurements were performed with I demonstrating stepwise structural rearrangements caused by water release.

“…Among the known SMMs, lanthanide complexes have attracted extensive attentions attributed to the lanthanide ions’ large unquenched orbital angular momentum resulting in the significant magnetic anisotropy, especially for the Dy(III) ion. Among the lanthanide SMMs, Dy(III) ion SMMs have been focused because of Dy(III) ion with unparalleled single‐ion anisotropy and the spin parity effect for a Kramers ion (odd number of 4 f electrons) . It was reported that the magnetic anisotropy of dysprosium ions is strongly influenced by the ligand field.…”

Two new 3, 5-heptanedione (β-diketonate) dysprosium complexes, namely, [Dy(L) 3 (phen)] (1) and [Dy(L) 3 (tmphen)] (2), have been designed and isolated by reactions of 3, 5-heptanedione with dysprosium chloride and auxiliary ligand under room temperature (L = 3, 5-heptanedione, phen = 1, 10-phenanthroline, tmphen = 3, 4, 7, 8-tetramethyl-1, 10-phenanthroline). Xray crystallographic analysis reveals that complexes 1 and 2 are mononuclear, and the Dy(III) ions are eight coordinated forming the square-anti-prismatic geometry. Complexes 1 and 2 were characterized by various means including elemental analysis, IR and UV spectroscopy. Magnetic studies indicate that both complexes 1 and 2 are single-molecule magnets (SMMs) under zero dc field. Notably, the auxiliary ligand plays an essential role in regulating their magnetism, which result in the essential magnetism difference between complexes 1 and 2.[a] S. Figure 8.

Under hydrothermal condition, a new three‐dimensional (3D) cobalt carboxylate metal‐organic framework Co3(H2O)L1.5(H2O)3 (H4L=1,4,5,8‐naphthalenetetracarboxylic acid) (1) has been successfully synthesized. Single‐crystal X‐ray diffraction, elemental analysis, IR spectroscopy, thermogravimetric analysis, powder X‐ray diffraction, and magnetic measurement for 1 were presented. 1 shows a new 3D framework with a 4,8‐connected {416.612}{44.62}2 topology. Crystal data for 1 are as follows: hexagonal cell; space group P6/m, with a=12.612(5) Å, b=12.612(5) Å, c=9.978(5)(3) Å, a;=90°, β=90°, and γ=120°; volume V=1374.5(15) Å3; and Z=2. The static magnetic behavior of 1 was conducted. The corresponding structural and magnetic parameters have been discussed in detail.
