A molecular tetraamminecopper(II)-trans-diamminecopper(II) tetracyanonickelate(II) coordination compound
摘要:
The title complex, [Ni4Cu4(CN)(16)(NH3)(12)] or {[Cu(NH3)(4)][cis-Ni(CN)(2)(mu-CN)(2)]-cyclo-[trans-Cu(NH3)(2)]-[cis-Ni(CN)(2)(mu-CN)(2)]}(2), is a dimeric C-2h symmetrical entity built from square-planar [Ni(CN)(4)](2-) anions as cis bridging ligands and (distorted) square-pyramidal copper centres. All of the atoms, except those of the three independent ammine groups, lie on a mirror plane. Copper is coordinated ammine and tetracyanonickelate ligands. This is a rare example of a discrete molecular cyano-copper-nickel complex.
