Synthesis,crystal structure and non-linear optical properties of a new cyanide-containing compound |

| Abstract: | Reaction of K3Fe(CN)6], NiCl2 and diethylenetriamine (dien) resulted in the formation of a cyanide-containing heterometallic compound Ni(dien)2]2Fe(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. |
