Trivanadium sulfide[1] is a metal rich sulfide of vanadium with chemical formula V3S.[2] It is metallic in appearance and conductivity.[3]

Properties

V3S melts around 1360°C.[4]

V3S forms a eutectic mixture with vanadium with a composition in atom %: V 82.2%, S 17.8% melting at 1312°C.[4] Although metallic, V3S is not known to be a superconductor.[5]

Structure

V3S is dimorphous.[6]

Alpha form

The alpha form α-V3S is stable over 950°C but can be quenched to a metastable state at room temperature. The crystals form in the body-centred tetragonal system with space group I42m with the unit cell dimensions: a = 9.470 c = 5.589 Å and unit cell volume of 501.2 Å3 with eight formula units per cell. Its density is 5.895 tonnes/m3.[6]

α-V3S is the prototype for a crystal structure type that includes AuPb3,[7] Zr3Ir,[8] Mo3P, and Ta3P.[9]

Beta form

The beta form β-V3S is stable below 825°C. The crystals form in the tetragonal system with space group P42/nbc with the unit cell dimensions a = 9.381 c = 5.939 Å, also with eight formulae per unit cell. Density is 5.939 tonnes/m3.[6]

β-V3S is the prototype for a crystal structure type that includes Ta3P.[9]
