Poly[zinc(II)-μ₂-azido-κ²N¹:N¹-μ₃-nicotinato-κ³N:O:O′]

Abstract

The title complex, [Zn(N3)(C6H4NO2)]n, formed from Zn cations, nicotinate and azide groups, exhibits a three-dimensional non-centrosymmetric covalent network. The coordin­ation sphere of the central metal ions is completed by an N3O2 five-coordinate coordination model showing distorted trigonal–bipyramidal geometry. Adjacent Zn atoms are bonded by μ2-carboxyl­ate groups and a μ2-azide bridge into one-dimensional helical double-stranded chains with the six-membered ring running along the a axis, and these chains are further linked by μ3-nicotinate groups via covalent bonds, extending into two-dimensional sheets and further generating a non-centrosymmetric three-dimensional covalent network.
