catena-Poly[(μ-anilido)(μ-1,2-dimeth-oxy-ethane-κ(3)-O,O':O)sodium]

Area of Science:

• Inorganic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Understanding the coordination behavior of alkali metal cations is crucial in inorganic chemistry.
• Anilide anions and ether ligands are common building blocks in coordination compounds.

Purpose of the Study:

• To elucidate the crystal structure and coordination environment of the title compound, [Na(C(6)H(5)NH)(C(4)H(10)O(2))].
• To investigate the coordination modes of anilide anions and 1,2-dimethoxyethane ligands around the sodium cation.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed to determine the molecular and crystal structure.
• The coordination geometry and bonding interactions were analyzed based on the crystallographic data.

Main Results:

• The sodium cation is coordinated by two anilide nitrogen atoms and three oxygen atoms from two 1,2-dimethoxyethane ligands.
• A distorted square pyramidal coordination polyhedron is observed around the sodium ion.
• The compound forms a polymeric chain structure parallel to the [100] direction, featuring Na(2)O(2) and Na(2)N(2) four-membered rings.

Conclusions:

• The anilide anions act as bridging ligands, and the 1,2-dimethoxyethane ligands exhibit a μ(2)-κ(3)-O,O' coordination mode.
• The observed polymeric structure arises from the specific coordination preferences of the sodium cation with these ligands.
• The hydrogen atom on the anilide NH group is not involved in intermolecular hydrogen bonding.
