Description:
Six new rare-earth metal tetracyanidoborates were prepared and characterized by single-crystal X-ray diffraction. Crystals of these salts contain co-crystallized solvent molecules, such as water, acetone, ethanol, or diethyl ether. In [La(EtOH) 3 (H 2 O) 2 {B(CN) 4 } 3 ] ( 1 ), [La(EtOH)(H 2 O) 4 {B(CN) 4 } 3 ] · Et 2 O ( 2 ), and [Y(EtOH)(H 2 O) 4 {B(CN) 4 } 3 ] · EtOH ( 6 ) the tetracyanidoborate anions are all or in part bonded to the RE 3+ ions, whereas in [Pr(H 2 O) 9 ][B(CN) 4 ] 3 · (CH 3 ) 2 CO ( 3 ), [Er(H 2 O) 8 ][B(CN) 4 ] 3 · (CH 3 ) 2 CO ( 4 ), and [Lu(EtOH)(H 2 O) 7 ][B(CN) 4 ] 3 · EtOH · 0.5H 2 O ( 5 ) the [B(CN) 4 ] – anions are not coordinated to the central metal atoms. Only in 1 , one of the three crystallographically independent [B(CN) 4 ] – anions acts as a bridging ligand.
