Micrometric 2D arrays of Ba(NO3)2 were spontaneously produced on a glass substrate through crystal growth induced by evaporation of water from viscous solutions containing polyvinyl alcohol (PVA). Specific trigonal microarrays were formed when the {111} face of Ba(NO3) 2 was parallel to the substrate. Aligned triangles, honeycomb frames, and thin rod arrangements were obtained by adjusting the concentrations of Ba(NO3)2 and PVA. The formation of the particular microarrays is achieved through zigzag growth of the cubic crystal in the thin polymer matrix.
