Silver(I) cyanoguanidine nitrate hydrate, Ag(C2N4H4)NO3·½H2O, was synthesized as the first cyanoguanidine solid-state complex in which monovalent Ag is coordinated through inner nitrogen N atoms. Its structure was characterized by single-crystal X-ray diffraction, crystallizing in the acentric orthorhombic space group P21212 with a = 10.670(3) Å, b = 18.236(5) Å, and c = 3.5078(9) Å. The differing chemical bondings of Ag(C2N4H4)NO3·½H2O and Ag(C2N4H4)3NO3 were compared on the basis of first-principle calculations.

AbstractThe hydrothermal reaction of Zn(II) nitrate hydrate with 5-(pyridin-4-yl)isophthalic acid (H2L) yields the complex [Zn2(L)2(H2O)2] · 2(H2O) (1), which has been characterized by single crystal X-ray diffraction, IR spectroscopic, elemental, and thermogravimetric analyses. Complex 1 exhibits a 3-nodal (3,6)-connected 2D net structure with (4.62)2(42.610.83)(63)4 topology. Its luminescence property was investigated, but the results show that the coordination to the zinc atom has no significant effect on the emission of the ligand.

Crystals of hypoxanthinium (6-oxo-1H,7H-purin-9-ium) nitrate hydrates were investigated by means of X-ray diffraction at different temperatures. The data for hypoxanthinium nitrate monohydrate (C5H5N4O+·NO3 −·H2O, Hx1) were collected at 20, 105 and 285 K. The room-temperature phase was reported previously [Schmalle et al. (1990). Acta Cryst. C46, 340–342] and the low-temperature phase has not been investigated yet. The structure underwent a phase transition, which resulted in a change of space group from Pmnb to P21/n at lower temperature and subsequently in nonmerohedral twinning. The structure of hypoxanthinium dinitrate trihydrate (H3O+·C5H5N4O+·2NO3 −·2H2O, Hx2) was determined at 20 and 100 K, and also has not been reported previously. The Hx2 structure consists of two types of layers: the `hypoxanthinium nitrate monohydrate' layers (HX) observed in Hx1 and layers of Zundel complex H3O+·H2O interacting with nitrate anions (OX). The crystal can be considered as a solid solution of two salts, i.e. hypoxanthinium nitrate monohydrate, C5H5N4O+·NO3 −·H2O, and oxonium nitrate monohydrate, H3O+(H2O)·NO3 −.

Deposisi lapisan TiO2 didoping Cu telah berhasil ditumbuhkan dengan menggunakan metoda Liquid Phase Deposition (LPD). Lapisan TiO2-Cu dibuat dengan menggunakan material Ammonium hexafluorotitanate ((NH4)2TiF6), Copper (II) Nitrate hydrate (Cu(NO3)2·xH2O), dan Hexamethylen tetramine (C6H12N4). Dalam penelitian ini dilakukan variasi lama penumbuhan lapisan yaitu 3 jam, 5 jam, 7 jam dan 10 jam. Lapisan TiO2-Cu dikarakterisasi menggunakan Spektrometri Ultraviolet-Visible (UV-Vis) untuk menentukan energi gap melalui spektra difusi reflektansi. Hasil energi gap yang diperoleh pada lapisan TiO2-Cu dengan variasi lama penumbuhan yaitu antara 3,26-3,30 eV.Kata kunci: Titanium dioksida (TiO2), Liquid Phase Deposition (LPD) dan doping
