What is the importance of Zeises salt?
201410357). The researchers have found that the compound strongly inhibits cyclooxygenase (COX) enzymes, but it shows low cytotoxicity against cancer cells. The observation indicates that Zeise’s salt works differently than Peyrone’s salt, an analog better known as the potent chemotherapy drug cisplatin, PtCl2(NH3)2.
What is wrong about zeise salt?
Zeise’s salt is diamagnetic. Oxidation state of Pt in Zeis’s salt is +2. All the Pt-Cl bond length in Zeise’s salt are equal. C-C bond length of ethylene moiety in Zeise’s salt longer than that of free ethylene molecule
What is zeise salt Class 12?
Zeise’s salt is K[PtCl3(η2−C2H4)]. The structure of the Zeise’s salt is shown in the figure. This salt was prepared by Danish pharmacist Zeise in 1830 . It is one of the compound of transition metals which was prepared earlier.
What is Zeise’s salt and ferrocene?
In Zeise’s salt, the Pt(II)consists of three π-type filled d-orbital which are dxy,dyz and dxz. Ferrocene is an organometallic compound and has C5 rotational axis and contains five perpendicular C2 axis. Ferrocene has a point group D5.

Why Zeise’s salt is diamagnetic?
In zeise’s salt Pt(II) is the central metal ion which is a square planar complex and the complex is diamagnetic. Central Pt 2+ ion coordinated with 3 Cl-ions and 1 ethene molecule in a square planar geometry while the 4 coplanar H’s are not coplanar with the 2 C’s.
Is Zeise’s salt organometallic?
Zeise’s salt was one of the first organometallic compounds to be reported. It was discovered by William Christopher Zeise, a professor at the University of Copenhagen, who prepared this compound in 1830 while investigating the reaction of PtCl4 with boiling ethanol.
What is the oxidation state of Pt in Zeise’s salt?
+ 2
The oxidation number of Pt in Zeise’s salt is + 2.
What is meant by Hapticity?
Hapticity is the coordination of a ligand to a metal center via an uninterrupted and contiguous series of atoms. The hapticity of a ligand is described with the Greek letter η (‘eta’). For example, η2 describes a ligand that coordinates through 2 contiguous atoms.
What is 18 electron rule with example?
Compounds that obey the 18-electron rule are typically “exchange inert”. Examples include [Co(NH3)6]Cl3, Mo(CO)6, and [Fe(CN)6]4−. In such cases, in general ligand exchange occurs via dissociative substitution mechanisms, wherein the rate of reaction is determined by the rate of dissociation of a ligand.
Is Zeise’s salt olefin?
The first olefin complex of a platinum group metal to be discovered was Zeise’s salt, K[C,H,PtCl,].
What is the oxidation of Pt?
Principles oxidation states of Pt are II and IV; with phosphine and CO ligands, 0 oxidation states are also stabilized. The II state is d8; these Pt(II) is almost invariably square-planar and are most frequently of the type MX2L2 (X=monodentate anion, L=donor ligand), which may exist as cis and trans isomers).
What is Zeise’s salt made of?
?) Zeise’s salt, potassium trichloro (ethylene)platinate (II), is the chemical compound with the formula K [ Pt Cl 3 (C 2 H 4 )]·H 2 O. The anion of this air-stable, yellow, coordination complex contains an η2 – ethylene ligand.
What is the activation energy of Zeise salt?
In Zeise’s salt and related compounds, the alkene rotates about the metal-alkene bond with a modest activation energy. Analysis of the barrier heights indicates that the π-bonding between most metals and the alkene is weaker than the σ-bonding.
What is the trans effect in Zeise’s salt?
The bonding in Zeise’s salt is further complicated by a phenomenon known as the trans effect, which is that for molecules with square planar geometries, like Zeise’s salt, certain groups will remove electron density from, and thereby weaken the bonding of, the group trans (opposite) to them.
What is the rotational barrier in Zeise’s salt?
In Zeise’s salt and related compounds, the alkene rotates about the metal-alkene bond with a modest activation energy. Analysis of the barrier heights indicates that the π-bonding between most metals and the alkene is weaker than the σ-bonding. In Zeise’s anion, this rotational barrier has not been assessed.
