Chemistry
Molecular Structure of Iodine heptafluoride (CAS NO. 16921-96-3):
EINECS: 240-981-4
Chemical Name: Iodine heptafluoride
Molecular Formula: F7I
Molecular Weight: 259.893292 g/mol
XLogP3-AA: 4.7
H-Bond Donor: 0
H-Bond Acceptor: 7
Canonical SMILES: FI(F)(F)(F)(F)(F)F
InChI: InChI=1S/F7I/c1-8(2,3,4,5,6)7
InChIKey: XRURPHMPXJDCOO-UHFFFAOYSA-N
Boiling Point: 4.7 °C
Density: 2.6 g/cm3
Production
Iodine heptafluoride is produced by passing F2 through liquid IF5 at 90 °C, then heating the vapours to 270 °C. Iodine heptafluoride also can be prepared from fluorine and dried PdI2 or KI to minimize the formation of IOF5, then refining by hydrolysis.
Safety Profile
Safety Information of Iodine heptafluoride (CAS NO. 16921-96-3):
Risk Statements: 8-14-34
R8 :Contact with combustible material may cause fire
R14 :Reacts violently with water
R34:Causes burns
Safety Statements: 3/7-9-17-36/37/39-45
S3:Keep in a cool place
S7:Keep container tightly closed
S9:Keep container in a well-ventilated place
S17:Keep away from combustible material
S36/37/39:Wear suitable protective clothing, gloves and eye/face protection
S45:In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)
RIDADR: 3157
Mixtures with hydrogen explode on exposure to sparks or heat. Ignition on contact with carbon; combustible gases (e.g., methane or carbon monoxide); other organic compounds (e.g., benzene; light petroleum; ethanol; ether; cellulose; grease; oils).

Specification
Iodine heptafluoride with cas registry number of 16921-96-3 is also known as Iodine fluoride (IF7) ; Iodine(VII) fluoride .It melt at 4.5 °C to form colourless crystals. It has an unusual pentagonal bipyramidal structure. The molecule can undergo a pseudorotational rearrangement like the Berry mechanism but for a hepta coordinated system.
