ABSTRACT
In the title compound, {[NiCl(2)(C(19)H(17)N(5)O(2))(2)]·4C(3)H(7)NO}(n), the Ni(II) atom is located on an inversion centre and is in a six-coordinated octahedral geometry, formed by four pyridine N atoms from four N(2),N(6)-bis[(pyridin-3-yl)methyl]pyridine-2,6-dicarboxamide (BPDA) ligands occupying the equatorial plane and two chloride anions at the axial sites. The bidentate bridging BPDA ligands link the Ni(II) atoms into a two-dimensional corrugated grid-like flexible layer with a (4,4)-connected topology, which consists of left- and right-handed helical chains sharing the common Ni(II) atoms. Investigation of the thermal stability shows that the network is stable up to 573 K.
