Description / Table of Contents:
Mercury Compounds with Cyancarbanions. I . Synthesis and Crystal Structure of Dimercury(I)-bis(tricyanmethanide)With the triclinic unit cell, space group P1, with the lattice constants a = 5.2794(1) Å, b = 9.9279(1) Å, c = 11.3376(2) Å, α = 71.004(4)°, β = 76.459(2)° and γ = 74.601(4)° are two formula units. The three-dimensional network, which characterizes the structure, results from dimercury(I) ions with sp3 hybridization, which form beside the homonuclear metal bonding three covalent bonds to cyanonitrogen atoms. The tricyanmethanide ion acts by losing symmetry as a tridentate ligand.
Notes:
Innerhalb der triklinen Elementarzelle, Raumgruppe P1, mit den Gitterkonstanten a = 5,2794(1) Å, b = 9,9279(1) Å, c = 11,3376(2) Å, α = 71,004(4)° und β = 74,601(4)° befinden sich zwei Formeleinheiten. Das den Strukturaufbau charakterisierende dreidimensionale Netzwerk resultiert aus sp3-hybridisierten Diquecksilber(I)-ionen, die neben der homonuklearen Metallbindung drei weitere kovalente Bindungen zu Cyanstickstoffatomen ausbilden. Das Tricyanmethanidion wirkt unter Symmetrieverlust als dreizähniger Ligand.
