| Abstract: | Crystal Structure of the Basic Dimercury(I) Nitrates. II. Crystal Structure of Hg10(OH)4(NO3)6 . The crystal structure of Hg10(OH)4(NO3)6 has been determined from single crystal x-ray diffraction data. The unit cell is triclinic, space group P1 , a = 999.4(5), b = 909.9(5), c = 765.9(2) pm, α = 85.98(4), β = 78.70(3), γ = 109.83(5)°; Z = 1, R = 6.2%, Rw = 8.2%. Finite cationic chains (Hg2)5(OH)4(NO3)2]4+ are joined together by weak van der Waals-type interactions between neighbouring Hg and O atoms, thus forming ribbons running along 100]. The coordination sphere of the Hg atoms is completed by further nitrate ions, which lead to the formation of a loose framework. Thereby the metal atoms are not surrounded by simple coordination polyhedra. |
