Typical of Pt(IV), the metal centers adopt an octahedral coordination geometry, {PtCl 6}. This geometry is achieved by forming a polymer wherein half of the chloride ligands bridge between the platinum centers. Because of its polymeric structure, PtCl 4 dissolves only upon breaking the chloride bridging ligands. Thus, addition of HCl give H 2 ...
Platinum(II) chloride describes the inorganic compounds with the formula Pt Cl 2.They are precursor used in the preparation of other platinum compounds. Platinum(II) chloride exists in two crystalline forms (), but the main properties are somewhat similar: dark brown, insoluble in water, diamagnetic, and odorless.
Cisplatin is administered intravenously as short-term infusion in normal saline for treatment of solid and haematological malignancies. It is used to treat various types of cancers, including sarcomas, some carcinomas (e.g., small cell lung cancer, squamous cell carcinoma of the head and neck and ovarian cancer), lymphomas, bladder cancer, cervical cancer, [9] and germ cell tumors.
The polyhedral symbol is sometimes used in coordination chemistry to indicate the approximate geometry of the coordinating atoms around the central atom. One or more italicised letters indicate the geometry, e.g. TP-3 which is followed by a number that gives the coordination number of the central atom. [1]
Cisplatin, PtCl 2 (NH 3) 2, is a coordination complex of platinum(II) with two chloride and two ammonia ligands.It is one of the most successful anticancer drugs. A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands ...
The anion features a platinum atom with a square planar geometry. The salt is of historical importance in the area of organometallic chemistry as one of the first examples of a transition metal alkene complex and is named for its discoverer, William Christopher Zeise.
The coordination geometry of an atom is the geometrical pattern defined by the atoms around the central atom. The term is commonly applied in the field of inorganic chemistry, where diverse structures are observed. The coordination geometry depends on the number, not the type, of ligands bonded to the metal centre as well as their locations.
Hexaammineplatinum(IV) chloride is the chemical compound with the formula [Pt(NH 3) 6]Cl 4. It is the chloride salt of the metal ammine complex [Pt(NH 3) 6] 4+. The cation features six ammonia (called ammines in coordination chemistry) ligands attached to the platinum(IV) ion. It is a white, water soluble solid.
