Single crystals of molybdenum‐incorporated tris(thiourea)zinc(II) sulfate (MoZTS) are grown by the slow evaporation solution growth technique. Crystal composition as determined by single‐crystal X‐ray diffraction analysis reveals that it belongs to the orthorhombic system with space group Pca 2 1 and cell parameters a = 11.153 (2), b = 7.7691 (14), c = 15.408 (3) Å, V = 1335.14 (4) Å 3 and Z = 4. The surface morphological changes are studied by scanning electron microscopy. The vibrational patterns in FT–IR are used to identify the functional group and TGA/DTA (thermogravimetric analysis/differential thermal analysis) indicates the stability of the material. The structure and the crystallinity of the material were confirmed by powder X‐ray diffraction analysis and the simulated X‐ray diffraction (XRD) closely matches the experimental one with varied intensity patterns. The band gap energy is estimated using diffuse reflectance data by the application of the Kubelka–Munk algorithm. The relative second harmonic generation (SHG) efficiency measurements reveal that MoZTS has an efficiency comparable to that of tris(thiourea)zinc(II) sulfate (ZTS). Hirshfeld surfaces were derived using single‐crystal X‐ray diffraction data. Investigation of the intermolecular interactions and crystal packing via Hirshfeld surface analysis reveal that the close contacts are associated with strong interactions. Intermolecular interactions as revealed by the fingerprint plot and close packing could be the possible reasons for facile charge transfer leading to SHG activity.
