title: Tetra-kis[μ(3)-4-nitro-N-(5-phenyl-1,3,4-oxadiazol-2-yl)benzamidato]tetra-kis-[methano-lsodium(I)].
abstract: In the title compound, [Na(4)(C(15)H(9)N(4)O(4))(4)(CH(3)OH)(4)], the N(3)O(3) environment around the Na(+) ion is distorted octa-hedral. In the unit cell, four Na(+) ions are bridged by four Schiff base anions, leading to a tetra-nuclear complex with -4 symmetry. O-H⋯N hydrogen bonds between the methanol mol-ecule and the Schiff base anion stabilize the structural set-up.
