摘要：
Hg[B(CN)(4)](2) (1) is synthesised by the reaction between Hg(NO3)(2) and K[B(CN)(4)](2). In a comproportionation reaction of 1 with elemental mercury the corresponding mercury(I) salt Hg-2[B(CN)(4)](2) (2) is obtained. The compounds were characterised by vibrational- and NMR-spectroscopy, and their crystal structures were determined. Hg[B(CN)(4)](2) crystallizes in the trigonal system in the space group Oral with a = 781.75(3) pm, c = 601.68(2) pm, V = 318.44(2) Angstrom(3), and one formula unit per unit cell. For Hg-2[B(CN)(4)](2) an orthorhombic unit cell with a = 568.9(1) pm, b = 3280.9(7) pm, c = 601.68(2) pm, V = 1389.6(5) Angstrom, and Z = 4 is observed.
