Tri-μ-oxido-bis­[(5,10,15,20-tetra­phenyl­porphyrinato-κ(4) N)niobium(V)]

In the title dinuclear Nb(V) compound, [Nb(2)(C(44)H(28)N(4))(2)O(3)], each Nb atom is seven-coordinated with three bridging O atoms and four N atoms from a chelating tetra­phenyl­porphyrinate anion. The Nb—O bond lengths range from 1.757 (6) to 2.331 (6) Å, and the average (niobium–pyrrole N atom)...

Sumario:In the title dinuclear Nb(V) compound, [Nb(2)(C(44)H(28)N(4))(2)O(3)], each Nb atom is seven-coordinated with three bridging O atoms and four N atoms from a chelating tetra­phenyl­porphyrinate anion. The Nb—O bond lengths range from 1.757 (6) to 2.331 (6) Å, and the average (niobium–pyrrole N atom) distance is 2.239 Å. In the dinuclear mol­ecule, the Nb⋯Nb separation is 2.8200 (8) Å, and the dihedral angle between the two porphyrinate mean planes is 5.4 (1)°. Weak inter­molecular C—H⋯π inter­actions are present in the crystal structure.
