KMnAg3(CN)6, a new triply interpenetrating network solid

Area of Science:

• Crystal structure analysis
• Coordination chemistry
• Materials science

Background:

• The MAg(3)(CN)(6) framework is a known structure type with potential applications in materials science.
• Manganese-containing coordination compounds are of interest due to their diverse electronic and magnetic properties.

Purpose of the Study:

• To describe the single-crystal structure of a novel potassium manganese tris[dicyanoargentate(I)] compound.
• To identify the structural characteristics of this first Mn-containing example of the triply interpenetrating MAg(3)(CN)(6) type.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed to determine the atomic arrangement.
• Crystallographic data was collected and refined to establish the precise structure.

Main Results:

• The single-crystal structure of potassium manganese tris[dicyanoargentate(I)], KMnAg(3)(CN)(6), was successfully elucidated.
• This compound represents the first reported instance of a manganese-incorporating member within the triply interpenetrating MAg(3)(CN)(6) structural family.
• The potassium (K(+)) cation occupies an ordered interstitial site, resulting in the formation of a chiral space group.

Conclusions:

• The discovery of KMnAg(3)(CN)(6) expands the known structural diversity of the MAg(3)(CN)(6) framework.
• The ordered placement of K(+) ions and the resulting chirality are key features of this novel manganese coordination compound.
