Synthesis and structure of the polymeric complex [Ag-2(Ph3P)(2)B10H10] (n)

A method for the synthesis of the silver(I) complex with the closo-decaborate anion and triphenylphosphine [Ag-2(Ph3P)(2)B10H10] (n) was developed and the structure of this complex was studied. The polymeric chain of the complex is formed with participation of Ag(I) atoms, which coordinate the B10H (10) (2-) anions through the apical (B(1)-B(2), B(9)-B(10)) and equatorial (B(3)-B(6), B(5)-B(8)) edges, the metalligand bonding occurring through three-center two-electron bonds (MHB). The P atoms of two triphenylphosphine molecules are also incorporated in the inner coordination sphere of the metal: the CN of the silver atom is 4 + 1.
