WebApr 18, 2024 · Answer is: formula of the complex is [Cr(NH₃)₂(SCN)₄] ⁻. This complex has negative charge (-1) because chromium (central atom or metal) has oxidation number +3, first ligand ammonia has neutral charge and second ligand thiocyanate has negative oxidation number -1: +3 + 2 ·0 + 4·(-1) = -1. Webthe presence of Cr3+ ion. The as-synthesized structure formula, K[Cr(C 9H 7N) 2(SCN) 2][Zn(SCN) 4], was indicated by using XRD and SEM-EDX analysis. The presenting of quinoline and thiocyanate as ligands were identified from the as-synthesized FT-IR spectra. Its reduction potential showed the potential properties as battery material up to 0.45 V. bis method for salt
