Synthesis and structures of p-tert-butyltetrathiacalix[4]arene-dihydrides of Mo(V) and W(IV)
The reaction of zero-valent molybdenum and tungsten dinitrogen complexes cis-[M(N-2)(2)(PMe2Ph)(4)] (M = Mo, W) with 1 equiv of p-tert-butyltetrathiacalix[4]arene (TC4A(OH)(4)) gave novel dihydrido complexes [TC4A(OH)(2)(O2MH2 (PMe2Ph)(3))] (M = Mo, W). The structures were determined by X-ray crystallography.
