Abstract A novel one-dimensional chain coordination polymer [Cu 6 (CN) 6 (phen) 4 ] n 1 was synthesized from the simple hydrothermal reaction of Cu(CH 3 COO) 2 ·H 2 O, K 3 [Fe(CN) 6 ] and phen·H 2 O. With phen, CuCN exhibits a novel B–C–B–C chain array, namely the infinite chain is propagated via alternately three-coordinate (B) and four-coordinate (C) sites of monovalent Cu ions. It should also be noticed that the compound is the first example where the parent chain not only exhibits the [Cu(phen)] + side arm, but also is directly bound to the chelate ligand. Moreover, the third-order non-linear optical property of compound 1 was also investigated and it shows the reverse saturable absorption and self-focusing performance.

Gadolinium and indium co-doped CdO thin films were prepared by a pulsed laser deposition method. The XRD and XPS results indicated that Gd3+ and In3+ ions occupied locations in the interstitial positions and/or Cd2+-ion vacancies in the CdO lattice. The FESEM images showed that the films were homogeneous and consisted of nanograins with a size range of 23–40 nm. The optical band gap of the CdO thin films can be engineered over a wide range of 2.72–3.56 eV by introducing Gd and In dopants. Such transparent semiconducting Gd and In co-doped CdO films were then grown on p-type Si substrates to fabricate n-CdO/p-Si heterojunction devices. The important junction parameters such as the series resistance (Rs), ideality factor (n) and Schottky barrier height (Φb) were determined by analysing different plots from the current density–voltage (J–V) characteristics. The obtained results indicated that the electrical properties of the heterojunction diodes were controlled by the dopant concentration. The p-Si/n-Cd1−x−yGdxInyO heterojunction diode showed the best values of open circuit voltage, Voc = 1.04 V and short circuit current density, Jsc = 11.4 mA cm−2 under an illumination intensity of 100 mW cm−2, which was suitable for solar cell applications.

A cobalt(II) thiocyanate complex [Co(py)4(NCS)2] 1 (py = pyridine) has been synthesized by low-temperature solid-state reaction. Single crystal X-ray analysis reveals that 1 possesses a one-dimensional (1-D) zigzag chain structure. Each Co ion is symmetrically coordinated by four pyridine ligands and also coordinates with two NCS− anions. Compound 1 was characterized by elemental analyses, IR spectra and UV-visible spectra. The third-order non-linear optical (NLO) properties were also investigated and they exhibit non-linear absorption and self-defocusing performance with modulus of the hyperpolarizability 9.46 × 10−30 esu for 1 in a 3.6 × 10−4 mol dm−3 DMF solution.

The new polyoxometalate double-supporting transition metal complexes, {[Co(phen)2]2C2O4} {H2P O44[Co(phen)2H2O]2}·7H2O (1) (phen = 1,10-phenanthroline) have been hydrothermally synthesized and characterized by single crystal X-ray analysis, IR, XPS, ESR and elemental analysis. Compound 1 is composed of a highly reduced tetra-capped pseudo-Keggin polyoxoanion supporting two transition metal complexes, a binuclear cobalt complex cation and lattice water. The magnetism and third-order non-linear optical properties of 1 have also been studied.

Reaction of K3[Fe(CN)6], NiCl2 and diethylenetriamine (dien) resulted in the formation of a cyanide-containing heterometallic compound [Ni(dien)2]2[Fe(CN)6]·4H2O 1. The structure consists of two octahedral [Ni(dien)2]2+ cations, one octahedral [Fe(CN)6]4− anion and four crystallization water molecules, which are held together by hydrogen-bonding interactions. Its TG curve exhibits two stages of mass loss. Compound 1 in DMF solutions has a very strong third-order non-linear optical (NLO) behavior with an absorption coefficient and refractive index α2 = 1.10 × 10−11 m w−1, n 2 = −3.05 × 10−19 m2 w−1, respectively, and third-order NLO susceptibility χ(3) 4.34 × 10−13 esu.
