Crystals of the title compound, (C24H20P)2[UO2Cl 4].-CH2Cl2, contain pseudo-octahedral tetrachlorouranyl anions having approximate D4h, and exact Ci point symmetry. The asymmetric unit contains two such anions, each distinct and isolated, and each unperturbed by close anion-anion packing, hydrogen bonding or the presence of small polarizing cations. The U=O bond lengths are 1.75 (1) and 1.77 (1) A, and provide points of reference for the recently reported oxouranium (phosphorane iminato) complex containing the O=U=N- group.
