[4] If excess acids are removed, PtCl 4 crystallizes from aqueous solutions in large red crystals of pentahydrate PtCl 4 ·5(H 2 O), [5] which can be dehydrated by heating to about 300 °C in a current of dry chlorine. The pentahydrate is stable and is used as the commercial form of PtCl 4. Treatment of PtCl 4 with aqueous base gives the [Pt(OH ...
PTCL had started with 10 digit numbers for landline telephones. The first three (in case of smaller cities, 4 or 5) signified the area code (e.g. 042 for Lahore) and the rest (7 for large cities, 6 or 5 for smaller ones) were the subscribers number.
Chloropentammineplatinum chloride is an inorganic compound with the formula [PtCl(NH 3) 5]Cl 3. It is a chloride salt of the coordination complex [PtCl(NH 3) 5] +. It is a white, water soluble solid. The compound is prepared by treating potassium hexachloroplatinate with aqueous ammonia: [1] K 2 PtCl 6 + 5 NH 3 → [PtCl(NH 3) 5]Cl 3 + 2 KCl
PTCL-NOS, the most common subtype of PTCL, is aggressive and predominantly nodal. There are two morphologic variants: the T-zone lymphoma variant and the lymphoepithelioid cell variant. [4] [5] T-zone lymphoma is so named for its involvement in a specific area of the lymph node that consists of a dense accumulation of T-cells. [6]
Bis(triphenylphosphine)platinum chloride is a metal phosphine complex with the formula PtCl 2 [P(C 6 H 5) 3] 2. Cis- and trans isomers are known. The cis isomer is a white crystalline powder, while the trans isomer is yellow. [3] Both isomers are square planar about the central platinum atom. The cis isomer is used primarily as a reagent for ...
PtCl 4 2− + 2 PPh 3 → cis-PtCl 2 (PPh 3) 2 + 2 Cl −. The anti-cancer drug Cisplatin can similarly be prepared: [1] PtCl 4 2− + 2 NH 3 → cis-PtCl 2 (NH 3) 2 + 2 Cl −. Enedithiolates displace all four chloride ligands to give bis complexes. [3] Reduction gives colloidal platinum of potential interest for catalysis. [4]
Magnus's green salt is the inorganic compound with the formula [Pt(NH 3) 4][PtCl 4]. This salt is named after Heinrich Gustav Magnus, who, in the early 1830s, first reported the compound. The compound is a linear chain compound, consisting of a chain of platinum atoms. It is dark green, which is unusual for platinum compounds.
Zeise's dimer, [(η 2-C 2 H 4)PtCl 2] 2, derived from Zeise's salt by elimination of KCl followed by dimerisation. COD-platinum dichloride, (cyclooctadiene)PtCl 2, derived from platinum(II) chloride and 1,5-cyclooctadiene, is a common platinum(II) alkene complex. Many other ethylene complexes have been prepared.
