Abstract:
Heating a solid mixture of (NH4)(3)VS4, CuCl, PPh3, and NEt4Br at 100 degrees C for 10 h and extraction with CH2Cl2 yielded [VS4(CuPPh3)(4)Br]. CH2Cl2. Crystallographic data: Triclinic, , a = 15.189(3), b = 20.093(6), c = 12.031(3) Angstrom, alpha = 102.39(2), beta = 100.05(2), gamma = 82.86(2)degrees, V = 3517(3) Angstrom(3), and Z = 2. The configuration of the VS4Cu4Br core can be described as a distorted cubans with an additional face. The V atom has retained the tetrahedral geometry of the free [VS4](3-) moiety. The four Cu atoms have three different coordination environments, strongly distorted tetrahedral, nearly trigonal planar, and strictly trigonal planar. The infrared, electronic, and V-51 NMR spectra have also been reported.
