Herein, we describe the synthesis, crystal structure, and electronic properties of {[K(dmso)(HO)][Ni(Hmpba)]·dmso·2HO} () and [Ni(HO)][Ni(Hmpba)]·3CHOH·4HO () [dmso = dimethyl sulfoxide; CHOH = methanol; and Hmpba = 1,3-phenylenebis(oxamic acid)] bearing the [Ni(Hmpba)] helicate, hereafter referred to as {Ni}. SHAPE software calculations indicate that the coordination geometry of all the Ni atoms in 1 and 2 is a distorted octahedron (O) whereas the coordination environments for K1 and K2 atoms in 1 are Snub disphenoid J84 (D) and distorted octahedron (O), respectively. The {Ni} helicate in is connected by K counter cations yielding a 2D coordination network with topology.
