An extended network of twenty-membered K6Se6P4N4 rings: X-ray structure of {[(THF)K[ButN(Se)P(μ-NBut)2P(Se)N But]K(THF)2]2}∞
Abstract
The partially THF-solvated dipotassium salt of the novel bis-chelating dianion [ButN(Se)P(μ-NBut)2P(Se)NBut ]2− forms an infinite network of twenty-membered K6Se6P4N4 rings involving two types of K···Se interactions.
