Abstract: | Air‐stable, orange‐red single crystals of [{ReN(PMe2Ph)3}{ReO3N}]2 are formed when mer‐[ReNCl2(PMe2Ph)3] reacts with strong bases in MeOH. The resulting centrosymmetric tetranuclear complex contains each two {ReN(PMe2Ph)3}2+ and {ReO3N}2? building blocks. They are connected by two oxygen and two nitrogen atoms giving an almost planar {Re4O2N2} ring. The Re–N–Re bridges are only slightly bent (175.2(2)°), while the Re–O–Re angles are 160.9(1)°. The coordination environment of the rhenium atom in the nitridotrioxorhenate(VII) anion is a slightly distorted tetrahedron with O–Re–O and O–Re–N angles between 108.7(1)° and 111.3(1)°. |
