Tetronic Acid

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.

A new bi-capped Keggin heteropoly molybdovanadated derivative, [Co (en)3]2[SiMo8V6O42]∙6H2O (1) (en = ethylendiamine) has been hydrothermally synthesized and structurally characterized by the elemental analysis, IR, XPS and single crystal X-ray diffraction. The crystal structure analysis reveals that compound 1 consists of [Co (en)3]2+transition metal coordination fragment and the [SiMo8V6O42]4-building blocks, which are linked together via hydrogen-bonding interactions to form a new 3-D supramolecular networks.

Synthesis and characterization of (1E)-1-(4-chlorophenyl)-N-hydroxy-3-(1H-imidazol-1-yl)propan-1-imine (4) are reported. X-ray crystal structure of the title oxime4confirmed its assigned (E)-configuration. The compound crystallizes in the monoclinic space groupP21/cwitha=13.4292(3) Å,b=8.8343(2) Å,c=11.1797(3) Å,α=90°,β=108.873(2)°,γ=90°,V=1255.03(5) Å3, andZ=4. The molecules are packed in crystal structure by weak intermolecularO–H⋯Nhydrogen bonding interactions. Compound4is a useful intermediate for the synthesis of new imidazole-containing antifungal agents.

The synthesis of RbHCN2 was carried out by reaction of cyanamide with rubidium amide in liquid ammonia. The crystal structure has been determinedo by x-ray powder methods (orthorhombic, P21,21,21, a = 7.299(1), b = 9.435(1), c = 9.420(1) Å; Z = 8). The anion is slightly bent (174°) and exhibits two different bond lengths (C-N: 1.17, HN-C: 1.31 Å).
