  2. Calcium thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Calcium_thiocyanate

    Calcium thiocyanate refers to the salt Cs(SCN) 2. It is a colorless solid. According to X-ray crystallography, it is a coordination polymer. The Ca 2+ ions are each bonded to eight thiocyanate anions, with four Ca-S and four Ca-N bonds. The motif is reminiscent of the fluorite structure. [1]

  3. Thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Thiocyanate

    Thiocyanate [6] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase. [7] [8] [9] Thus the complete absence of thiocyanate or reduced thiocyanate [10] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.

  4. Organic thiocyanates - Wikipedia

    In methyl thiocyanate, N≡C and C−S distances are 116 and 176 pm. By contrast, N=C and C=S distances are 117 and 158 pm in isothiocyanates. [7] Typical bond angles for C−S−C are 100°. [3] By contrast C−N=C in aryl isothiocyanates is 165°. Again, the thiocyanate isomers are quite different with C−S−C angle near 100°.

  5. Calcium silicate hydrate - Wikipedia

    en.wikipedia.org/wiki/Calcium_silicate_hydrate

    It has a layered geometry with calcium silicate sheet structure separated by an interlayer space. The silicates in C-S-H exist as dimers, pentamers and 3n-1 chain units [ 9 ] [ 10 ] (where n is an integer greater than 0) and calcium ions are found to connect these chains making the three dimensional nano structure as observed by dynamic nuclear ...

  6. Isothiocyanate - Wikipedia

    en.wikipedia.org/wiki/Isothiocyanate

    Allyl thiocyanate isomerizes to the isothiocyanate: [4] CH 2 =CHCH 2 SCN → CH 2 =CHCH 2 NCS. Isothiocyanates can be prepared by treating organic dithiocarbamate salts with lead nitrate or tosyl chloride. [5] [6] Synthesis of phenyl isothiocyanate. Isothiocyanates may also be accessed by the fragmentation reactions of 1,4,2-oxathiazoles. [7]

  7. Cyanate - Wikipedia

    Structurally the isomers can be distinguished by the geometry of the complex. In N-bonded cyanate complexes the M−NCO unit sometimes has a linear structure, but with O-bonded cyanate the M−O−C unit is bent. Thus, the silver cyanato complex, [Ag(NCO) 2] −, has a linear structure as shown by X-ray crystallography. [13]

  8. Mercury (II) thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Mercury(II)_thiocyanate

    Mercury(II) thiocyanate (Hg(SCN) 2) is an inorganic chemical compound, the coordination complex of Hg 2+ and the thiocyanate anion. It is a white powder. It is a white powder. It will produce a large, winding "snake" when ignited, an effect known as the Pharaoh's serpent .

  9. Sodium thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Sodium_thiocyanate

    Sodium thiocyanate (sometimes called sodium sulphocyanide) is the chemical compound with the formula NaSCN. This colorless deliquescent salt is one of the main sources of the thiocyanate anion . As such, it is used as a precursor for the synthesis of pharmaceuticals and other specialty chemicals . [ 2 ]
