Two novel organic amine templated lanthanide sulfates, layer (H3DETA)[Nd(H2O)(SO4)3] (I) and chain-like (H3DETA)[Ho(H2O)2(SO4)3] (II), are hydrothermally synthesized by using diethylenetriamine (DETA) as template, and are structurally characterized by ICP,
elemental analysis, X-ray single-crystal diffraction, X-ray powder diffraction, IR, and TG. Compound I is monoclinic with space group P21 and data of unit cell: a = 6.6518(13), b = 10.373(2), c = 11.091(2) ?, β = 93.61(3)°, V = 763.7(3) ?3, ρ

The chain coordination polymers [Na2(μ-H2O)(H2O)CB[5]]Cl2 · 6H2O (I), [Na3(μ-H2O)4(H2O)4(CNPy@CB[6])]Cl3 · 8H2O (II), and [Rb2(μ-H2O)2(CNPy@CB[6])]Cl2 · 8H2O (III) were prepared by heating (110°C) of a mixture of sodium or rubidium chloride, cucurbit[n]uril (CB[n], where n = 5, 6), 4-cyanopyridine, and water. According to X-ray diffraction data, binding of polynuclear cations with CB[n] in I–III occurs through coordination of the oxygen atoms of the cucurbit[n]uril portals to alkali metal atoms. Complexes I–III of the above composition isolated to the solid phase as supramolecular compounds with CB[n] were structurally characterized

The reaction of indium thiocyanate with bipyridine (4,4-Bipy) and urotropine (Ur) gave [H2(4,4′-Bipy)][In(H2O)2(NCS)4]2 (I) and [HUr]2[In(H2O)(NCS)5] · 2H2O (II), which were identified using elemental analysis, IR spectra, and thermogravimetric analysis. The thermal decomposition of
compound I and II ends at 650 and 640°C, respectively, and gives In2O3. X-Ray diffraction analysis of compound I showed that complex anions in the crystal form chains through O-H…S hydrogen bonds. The anion chains form a close packing
of columns with bipyridine cations located in the voids.

A new Pd nitrate complex KCs[Pd(NO3)4]·0.5H2O is synthetized. Its crystal structure contains isolated complex anions [Pd(NO3)4]2−, cations K+, Cs+, and crystallization water. Square-planar coordination around Pd is achieved by oxygen atoms of monodentate nitrate ligands.
The coordinated nitrate ligands are all oriented in the same way, in a “basket”-like arrangement. The coordination around
Pd is completed to 4+1 by forming Pd...Pd contacts of 3.564 ?.
