Aurate(1-), tetrakis(cyano-κC)-, potassium (1:1), (SP-4-1)-

Description:

Aurate(1-), tetrakis(cyano-κC)-, potassium (1:1), (SP-4-1)-, with the CAS number 14263-59-3, is a coordination compound featuring a gold(I) ion coordinated to four cyanide ligands. This compound typically exhibits characteristics associated with gold(I) complexes, such as a relatively low oxidation state, which can lead to unique electronic properties. The presence of cyanide ligands contributes to its stability and solubility in polar solvents. The potassium ion serves as a counterion, balancing the overall charge of the complex. In terms of structure, the tetrakis(cyano) coordination suggests a tetrahedral geometry around the gold center, which is common for gold(I) complexes. The compound may exhibit interesting optical and electronic properties, making it of interest in various fields, including materials science and catalysis. Additionally, due to the presence of cyanide, it is important to handle this compound with caution, as cyanides are known to be toxic. Overall, this compound represents a fascinating example of coordination chemistry involving gold and cyanide ligands.

Potassium tetracyanoaurate(III)

Controlled Product

CAS: 14263-59-3

Potassium tetracyanoaurate(III) (K[AuCl4]) is a crystalline, intermetallic compound that has been used in the production of coatings, spherical particles, and electrochemical materials. The pentahydrate form has a diameter of 4.8-5.2 Å and a melting point of ~115°C. K[AuCl4] is stable in air and water but reacts with strong acids to form potassium chloride and potassium tetracyanocuprate(II). This substance also has an optimal pH range of 6-7 and an average solubility range of 0.05-0.1g/100mL at 20°C. The microstructure of K[AuCl4] is not well understood because it is difficult to isolate from other compounds during synthesis.
