Tetrakis(acetonitrile)copper(I) tetrafluoroborate is a complex compound of copper with acetonitrile as the ligand and tetrafluoroborate as the counterion.
Preparation
[edit]Tetrakis(acetonitrile)copper(I) tetrafluoroborate can be prepared starting from nitrosyl tetrafluoroborate, which is obtained from dinitrogen tetroxide and tetrafluoroboric acid. The nitrosyl salt is then reacted with metallic copper in acetonitrile, initially producing a green-blue copper(II) complex. This complex is reduced to the copper(I) complex by further reaction with metallic copper. By boiling with additional copper powder until decolorization, the copper(I) complex is obtained.[1]
Properties
[edit]Tetrakis(acetonitrile)copper(I) tetrafluoroborate forms colorless crystals in the orthorhombic crystal system in the space group Pna21 with the lattice parameters a = 23.882 Å; b = 8.3285 Å; c = 20.338 Å, and twelve unit cells. The compound is isomorphous with tetrakis(acetonitrile)copper(I) perchlorate and tetrakis(acetonitrile)silver(I) perchlorate.[2]
Use
[edit]Tetrakis(acetonitrile)copper(I) tetrafluoroborate can be reacted with methoxyisobutyl isonitrile to produce Tetrakis(methoxyisobutyl isonitrile)copper(I) tetrafluoroborate.[3] This compound is used to produce technetium(99mTc)-sestamibi.[4]
