(−)-β-Isosparteine copper(II) chloride

A Mimic Molecule of Blue Copper Protein Active Site [(−)-Sparteine-N,N‘](maleonitriledithiolato- S,S‘)copper(II)

“…Most copper(II) sparteine complexes could be obtained from the precursor complex, (SP)Cu(NO 3 ) 2 , because the nitrate ligand in this compound is very labile and easily undergoes ligand exchanges with various anions …”

“…Over the past three decades, several studies on copper(II) complexes of the neutral alkaloid (−)-sparteine (SP) have been reported. , The crystal structures of copper(II) sparteine complexes with chloride, nitrate, and acetate have been determined, and the copper(II) centers in these complexes are always found to have a distorted tetrahedral geometry …”

Crystal structure of sparteinium tetrachlorocuprate monohydrate-packing polymorph

“…The presence of two amine atoms in the structure of sparteine led to its use as a bidentate ligand in various complexes (e.g., involving copper [1][2][3][4][5][6][7][8][9][10][11][12][13]). Following quaternization of both nitrogen atoms in the molecule sparteine was used as a dication in metalloorganic copper salts [14,15].…”
