The new Reinecke-salt-like compounds K[Cr(NCS)4L ] (n = 1 or 2 L = o- or m-phenylenediamine, respectively) have been prepared by the reaction of K3[Cr-(NCS)6] with L and their thermal stabilities investigated.179 Diquinolino- and di-iodoquinolino-silver(i) iodide salts of the anions [Cr(NCS)6]3- and [Cr(NCS)4L2] (L = aniline, o- or p-toluidine) have been prepared and characterized.180 Chro-mium(m) thiocyanato-complexes with biguanide derivatives, K[Cr(NCS)4L] [L = phenyl-, p-chlorophenyl-, tolyl-, or 1-(p-chlorophenyl-5-isopropyl)biguanide], have been prepared by the reaction of K3[Cr(NCS)6] with L in anhydrous EtOH and their i.r. and electronic spectra reported.181 cis- and trans-[Cr(en)2(NH3XNCS)]2 + have been prepared and both shown to have a Amax value at 476 nm, but with the expected relative magnitudes of s values, cis > trans, as 120 to 80.182 The thermal decompositions of the salts [Cr(NH3)6 x(NCS)x](NCS)3 x (x = 0. 1. or 2) have been characterized. Under d.t.a. conditions [Cr(NH3)6](NCS)3 changes stepwise to [Cr(NH3)5(NCS)](NCS)2, trans-[Cr(NH3)4(NCS)2](NCS), and finally to merfac-[Cr(NH3)3(NCS)3].183... 

A single-crystal X-ray structural investigation of 2-(phenylazo)phenyl tellurium thiocyanate revealed the thiocyanato group to be bonded to the tellurium atom via the sulfur atom4. 

Golub et al. have shown that zirconium(IV) and hafnium(IV) form eight-coordinate complexes in solution with NCS" alone or in the presence of DMF 329, 333). The compounds (Et4N)2[M(NCS)8] (M = Zr, Hf) both contain iV -thiocyanato groups, as determined by infrared studies, and are isomorphous 61). Benzyl phenyl arsinic acid has been used as an extractant and, unlike most systems, hafnium complexes are extracted better than zirconium complexes in the presence of NCS" 302).

Substituents which are capable of activating both electrophilic and nucleophilic substitution have been termed pan-activating and the azido group falls into this category, together with such structural units as aromatic iV-oxide, arylazo, azoxy, thiocyanato, nitroso and phenyl. 

Verkade and Dhont1531 have treated 3,4-dimethyl-2-pyrazolin-5-one and 4-methyl-3-phenyl-2-pyrazolin-5-one with phenyldiazonium chloride, forming respectively 3,4-dimethyl-2-phenylazo-3-pyrazolin-5-one, m.p. 273°, and 4-methyl-3-phenyl-2-phenylazo-3-pyrazolin-5-one, m.p. 212°. 2,3-Dimethyl-l-phenyl-3-pyrazolin-5-one reacts with thio-oyanogen to give its thiocyanate salt and 2,3-dimethyl-l-phenyl-4-thiocyanato-3-pyrazolin-5-one, m.p. 125°.742...

Trichloromethyl groups in the 2-position of pyrido[2,3-t/]pyrimidines can be replaced by oxygen functionalities as shown by the reactions of 4-amino-6-thiocyanato-5-phenyl-2-(trichloromethyl)pyrido[2,3-t/]pyrimidin-7(8//)-one (38) and 7-ethoxy-6-thiocyanato-5-phenyl-2-(trichloromethyl)pyrido[2,3- /]pyrimidin-4-amine with water or ethanol.128...
