چکیده
The crystal structure of the title compound, [Ni(6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)]·6CH(3)OH, consists of a centrosymmetric hexa-nuclear [Ni(II) (6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)] mol-ecule and six methanol solvent mol-ecules. In the hexa-nuclear unit, the six octa-hedrally coordinated Ni(II) atoms are linked by four μ(1,1,1)-azide and four μ(1,1)-azide bridges, forming a face-sharing Ni(6)N(8) tetra-cubane-like unit with four missing corners. The Ni(II) atoms are further bridged by four μ(1,2)-carboxalate groups. Neighbouring hexa-nuclear units are connected via N-H⋯O hydrogen-bonding inter-actions into a three-dimensional structure. Although the H atoms of the methanol OH groups could not be located, O⋯N/O contacts between 2.65 and 2.86 Å suggest that these mol-ecules participate in hydrogen bonding.
