Summary
Alkali metal hydroxides react with diethyl zinc to form novel oxo-centered clusters. These clusters exhibit high symmetry and extended structures stabilized by weak metal-hydrogen interactions.
Area of Science:
- Organometallic Chemistry
- Inorganic Chemistry
- Materials Science
Background:
- Alkali metal hydroxides are common bases.
- Diethyl zinc is an organometallic reagent.
- Oxo-centered clusters are a class of metal-organic compounds.
Purpose of the Study:
- To investigate the reaction products of alkali metal hydroxides with diethyl zinc.
- To characterize the structure and properties of the resulting clusters.
- To explore the mechanistic implications and structural relationships to known zincates.
Main Methods:
- Reaction of alkali metal hydroxides with neat diethyl zinc.
- Crystallization of the reaction products.
- X-ray diffraction analysis to determine molecular and crystal structures.
- Analysis of bonding and intermolecular interactions.
Main Results:
- Formation of oxo-centered clusters with the general formula M2O(ZnEt2)n, where M = Na (n=3) or M = K, Rb (n=4).
- These clusters crystallize in highly symmetric space groups.
- Extended structures are formed, stabilized by weak alkali metal-hydrogen interactions.
- Structural similarities and differences to known (oxo)organozincates were identified.
Conclusions:
- The reaction provides a synthetic route to novel oxo-centered alkali metal-organozinc clusters.
- The observed high symmetry and extended structures highlight the role of weak interactions in supramolecular assembly.
- These findings contribute to the understanding of organozincate chemistry and cluster formation.

1.2K
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

For solutions containing mixtures of different cations, the identity of each cation can be determined by qualitative analysis. This technique involves a series of selective precipitations with different chemical reagents, each reaction producing a characteristic precipitate for a specific group of cations. Metal ions within a group are further separated by varying the pH, heating the mixture to redissolve a precipitate, or adding other reagents to form complex ions.
For instance, group IV...

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

4.1K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

18.8K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...
