7 - Handling and Storage

---

HANDLING
Directions for Safe Handling: Do not get in eyes, on skin, on
clothing. Do not breathe vapor. Avoid prolonged or repeated
exposure.
STORAGE
Conditions of Storage: Keep tightly closed.

---

8 - Exposure Controls / Personal Protection

---

ENGINEERING CONTROLS
Safety shower and eye bath. Use only in a chemical fume hood.
GENERAL HYGIENE MEASURES
Wash contaminated clothing before reuse. Wash thoroughly after
handling.
PERSONAL PROTECTIVE EQUIPMENT
Respiratory Protection: Use respirators and components tested and
approved under appropriate government standards such as NIOSH (US)
or CEN (EU). Where risk assessment shows air-purifying respirators
are appropriate use a full-face respirator with multi-purpose
combination (US) or type ABEK (EN 14387) respirator cartridges as
a backup to engineering controls. If the respirator is the sole
means of protection, use a full-face supplied air respirator.
Hand Protection: Compatible chemical-resistant gloves.
Eye Protection: Chemical safety goggles.

SIGNS AND SYMPTOMS OF EXPOSURE
To the best of our knowledge, the chemical, physical, and
toxicological properties have not been thoroughly investigated.
In contrast to inorganic mercury compounds, alkyl mercury
compounds rapidly pass through the placenta and blood brain
barrier. The peripheral and central nervous systems and the
kidney are major target organs. Methylmercury poisoning symptoms
result primarily from damage to the nervous system. The symptoms
are primarily characterized by loss of sensation in the hands
and feet and in areas around the mouth, diminution of vision
resulting in tunnel vision, ataxia, dysarthria, and hearing
loss. Severe poisoning produces blindness, coma and death. There
is a latent period of weeks to months before development of the
poisoning symptoms. Mercury shows a specificity to damage small
nerve cells in the cerebellum and visual cortex. Methylmercury
causes degeneration and necrosis of neurons in the focal areas
of the cerebral cortex, especially within the visual areas of
the occipital cortex and the granular layer of the cerebellum.
It has been found that methylmercury inhibits protein synthesis
in the brain before symptoms of poisoning appear and that
ALDRICH www.molbase.com
recovery of protein synthesis does not occur in granular cells
as it does recover in other neuronal cell types. Consumption by
pregnant women has caused serious neurological disorders in
their offspring resulting in mental retardation with cerebral
palsy. Acute exposure to nonlethal levels of methylmercyry
results in
ROUTE OF EXPOSURE
Skin Contact: Causes skin irritation.
Skin Absorption: Readily absorbed through skin. May be fatal if
absorbed through skin.
Eye Contact: Causes eye irritation.
Inhalation: Material is irritating to mucous membranes and upper
respiratory tract. May be fatal if inhaled.
Ingestion: May be fatal if swallowed.
TARGET ORGAN INFORMATION
Kidneys. Nerves.
CONDITIONS AGGRAVATED BY EXPOSURE
May cause nervous system disturbances.

  DOI：10.1016/s0022-328x(00)86760-1

  日期：1982.9

  Purple IrCl3(CCl2)(PPh3)2 results from reaction between IrHCl2(PPh3)3 and Hg(CCl3)2. X-ray crystal structure determination reveals an octahedral complex with trans-phosphine ligands and a short IrC distance to the CCl2 ligand of 1.872(7) Å, compatible with an iridiumcarbon double bond. Chloride is easily displaced from the dichlorocarbene ligand and the products which have been derived include IrCl3(CO)(PPh3)2

  紫色IrCl 3（CCl 2）（PPh 3）2是IrHCl 2（PPh 3）3与Hg（CCl 3）2反应的结果。X射线晶体结构测定揭示了具有反式膦配体的八面体配合物，与CCl 2配体的IrC距离较短，为1.872（7）Å，与铱碳双键兼容。氯化物很容易从二氯卡宾配体上取代，得到的产物包括IrCl 3（CO）（PPh 3）2，IrCl 3（CS）（PPh 3））2，IrCl 3（CNMe）（PPh 3）2，IrCl 3（CClNMe 2）（PPh 3）2，IrCl 3（CNHCH 2 CH 2 NH）（PPh 3）2和IrCl（CSCH 2 CH 2 S）- （PPh 3）2。
