The dinuclear gold(I) amidinate complex [Au2(Me2-form)2], 1, (Me2-form = 2,6-Me2-formamidinate) reacts with Hg(CN)2 to form a 2D
structure, 1·2Hg(CN)2·2THF. Each gold center interacts with two
Hg(CN)2 molecules. The Au···Au distance increases from 2.7 Å
in the starting dinuclear complex to 2.9 Å in the adduct. The gold
centers are connected to four nitrogen atoms with Au−N distances
in the range 2.13−2.51 Å. The cyanide stretch is shifted from 2192
cm-1 in the Hg(CN)2 to 2147 cm-1 in the adduct.
