Ever since their discovery, superconductivity in cuprates has motivated the search for materials with analogous electronic or atomic structure [1]. Here we present how soft chemistry approaches can be used to synthesize superconducting infinite layer nickelates from their perovskite precursor phase, using topotactic reactions [2]. We will discuss our preliminary understanding of aspects that are similar and different from the cuprates, as well as initial exploration of the compositional variations accessible in this materials system.
