Structure and Bonding
Nickel tetracarbonyl contains nickel in the zero oxidation state. It has 18 valence electrons, and is a tetrahedral molecule with four carbonyl (carbon monoxide) ligands attached to nickel. The CO ligands, in which the C and the O are connected by triple bonds, are covalently bonded to the nickel atom via the carbon ends. Electron diffraction studies have been performed on this molecule, and the Ni-C and C-O distances have been calculated to be 1.838(2) and 1.141(2) angstroms respectively.

Famous quotes containing the words structure and/or bonding:
“For the structure that we raise,
Time is with materials filled;
Our to-days and yesterdays
Are the blocks with which we build.”
—Henry Wadsworth Longfellow (1809–1882)
“Attachment to a baby is a long-term process, not a single, magical moment. The opportunity for bonding at birth may be compared to falling in love—staying in love takes longer and demands more work.”
—T. Berry Brazelton (20th century)
