The Crystal Structure of Antimony Pentachloride at -30°

Abstract: The 489' transformation in Na2C03 makes its first appearance at 67.5 mole yo. No level range is observed indicating that this transformation is not quite as spontaneous as its opposite member. The 361' transition in NaZC03 is not detectable until approximately 92.5 mole yo from which point its latent heat increases continuously. The X-ray data indicate that the upper and lower curves have approximately a 10 mole yo separation a t room temperature which explains the rapid decrease in the magnitude of the sponta… Show more

“…The similarity of the molecular and solid state structure came as a surprise, since PCl 5 as a molecule has a trigonal bipyramidal structure [3], but in the solid state it crystallizes as [(PCl 4 ϩ )(PCl 6 Ϫ )] [4]. SbCl 5 , also trigonal bipyramidal as a molecule [5], has the same structure in the solid state, according to an early x-ray analysis [6]. But changes in the vibrational, n.q.r, and Sb-Mößbauer spectra at low temperatures have already previously been interpreted as a dimerisation into [Cl 4 SbCl 2 SbCl 4 ], namely a double chlorine bridged (two edge sharing octahedral) structure like in Nb 2 Cl 10 [7,12].…”

“…From a stereochemical point of view they are of interest, since the antimony atom rarely remains five coordinate. Indeed only for SbCl, has fivecoordination been established (2). However, a phase change is thought to occur at low temperatures, resulting in a different structure.…”
