Аннотация


Tetraphenylphosphonium hexabromoosmate, [Ph4P]2[OsBr6] (I), has been structurally characterized after synthesis by interaction of sodium hexabromoosmate with tetraphenylphosphonium bromide in dimethyl sulfoxide. The phosphorus atoms of [Ph4P]+ cations have distorted tetrahedral coordination geometry (СPС angles are 106.23(11)113.23(10)), the PС bond lengths are 1.791(2)1.801(2) Å). In octahedral [OsBr6]2 anions the OsBr bond lengths equal 2.4752(2)-2.5020(3) Å, trans-BrOsBr angles are 180.
