Thiocyanate
There is no specific element with the symbol SCN on the periodic table. SCN commonly refers to the thiocyanate ion (SCN-) which is a polyatomic ion. It is a combination of sulfur (S), carbon (C), and nitrogen (N), commonly found in compounds.
This is usually called potassium thiocyanate, KSCN it contains the SCN- ion which is the sulfur analog of the OCN- cyanate ion.
It appears to be a Hydrated Cobalt-Sulfocyanide Complex The formula should be written like this Co(SCN)2(H2O)4. The (SCN) is called a thiocyanate group.

Beryllium in ionic form has a charge of +2. Thiocyanate is a polyatomic ion with a charge of -1. Since ionic compounds like beryllium thiocyanate are neutral, the positively charged ions (cations) and the negatively charged ions (anions) must balance---two -1 anions to balance out the +2 cation. Be2+ + 2 SCN- ---> Be(SCN)2

KSCN or K+ + SCN- when in aqueous solution
The scn is an ever-increasing number. It can be used to determine the "age" of the database and its component datafiles.The current system SCN can be queried using dbms_flashback.get_system_change_number.The SCN of the last checkpoint can be found in v$database.checkpoint_change#.The SCN is needed in a flashback table .. to scn ... statement.Within this context, SCN stands for System Change Number.

SCN - TV station - was created in 2003.
Sn(SCN)4 or Sn(SCN)2
Let's see. FeCl3 + H3PO4 -> FePO4 + 3HCl Looks like a double displacement with iron(III)phosphate and hydrochloric acid as products. Idealized, perhaps. I do not know if correct in nature.
Fe^3+ ion forms the complex with SCN- , forming [FeSCN]2+
FeCl3 + 6KSCN --> [Fe(SCN)6]-3 + 6K+ + 3Cl- This is a complex ion equation. K has a charge of +1 and Cl has a charge of -1 but since these form an aqueous solution, they are seperated. Put together, the equation cannot be balanced.
