AbstractA potassium tetranitratopalladate(II) with the composition K2[Pd(NO3)4] · 2HNO3 was synthesized by a simple solvothermal process in a glass ampoule. The new compound crystallizes in the monoclinic space group P21/c (no. 14) with the lattice parameters a = 1017.15(4), b = 892.94(3), c = 880.55(3) Å, and β = 98.13(1)° (Z = 2). The crystal structure of K2[Pd(NO3)4] · 2HNO3 reveals isolated complex [Pd(NO3)4]2− anions, which are surrounded by eight potassium cations and four HNO3 molecules. The complex anions and the cations are associated in layers which are separated by HNO3 molecules. K2[Pd(NO3)4] · 2HNO3 can thus be regarded as a HNO3 intercalation variant of β-K2[Pd(NO3)4]. The characterization is based on single-crystal X-ray and powder X-ray diffraction.

AbstractBis(2-aminopyrimidine-N)diaquabis(saccharinato-O)copper(II) di(2-aminopyrimidine), [Cu(sac-O)2(ampym-N)2(H2O)2] · 2ampym was synthesized and characterized by means of elemental analysis, IR and UV-vis spectroscopy, magnetic susceptibility, simultaneous TG, DTG, DTA techniques, and X-ray diffraction. The complex crystallizes in the monoclinic space group P21/c [a = 7.4697(5), b = 10.1679(5), c = 22.743(2)Å , β = 92.844(5), Z = 2, R = 0.0275, wR= 0.0757, V = 1725.26(19) Å3]. The copper atom is bonded to two ampym N atoms and two sac O atoms as well as to two water O atoms in trans positions in the geometry of a distorted octahedron. There are also two ampym moieties as solvate molecules in the unit cell. The crystal structure is stabilized by N-H· · ·O, O-H· · ·N and C-H· · ·O type hydrogen bonding interactions. Intermolecular π−π interactions between the phenyl rings of ampym groups and C-H· · ·π interactions also support the packing of the molecules. The thermal decomposition of the complex has been studied.

The synthesis and characterization of two new tetronic acid zinc (II) complexes of the empirical formulae [Zn(L–H)2(H2O)2] (1) and [Zn(L–H)2(H2O)(MeOH)]H2O(2) found within the same crystal are reported. The zinc ions bind through alkoxide and carbonyl groups of the ligand 3-methoxycarbonyl-5-phenyl tetronic acid (LH) as indicated byHNMR and X-ray crystallographic studies. These complexes promote intra- and intermolecular interactions, such as hydrogen bonding andπstacking, giving place to the formation of molecular aggregates.

The molecular structure of the title compound, C8H11N3O, is nearly planar despite the chair conformation of the morpholine moiety. In the crystal, the molecules form sheets parallel to the b axis, which are supported by non-classical hydrogen-bonding interactions between C—H functionalities and the O atom of morpholine and the 4-N atom of pyrazine, respectively. The title compound crystallizes in the monoclinic space group P21/c with four molecules in the unit cell.
