The structures of the synthesized complexes were characterized using spectroscopic such as 1H, 13C, 19F NMR, and FT-IR and elemental analysis techniques. The Pd(II) complex 2d, incorporating an N-heterocyclic carbene (NHC) and morpholine ligand, was structurally characterized by Xray crystallography. The crystal packing reveals N-H & ctdot;Br hydrogen bonds, C-H & ctdot;F/O interactions, and C-F & ctdot;it stacking, forming a 3D network stabilized by supramolecular interactions. The cytotoxicity of the synthesized compounds (2a-f) was evaluated using the MCF-7 cell line. The anticancer activity of palladium complexes against MCF-7 cells was revealed with IC50 values ranging from 48.13-151.02 mu M. The effect of complex 2b on the gene expression of the hERG1 K+ channel was determined using the RT-qPCR method. hERG1 potassium channel gene expression decreased at the 50 mu M complex 2b concentration at 24 h.eninfo:eu-repo/semantics/closedAccessN -heterocyclic carbene complexImidazolium saltsMorpholineHerg1 k + channelGene expressionX-ray crystallographyArticle135710.1016/j.molstruc.2025.1451932-s2.0-105026654797Q1WOS:001659434000001Q2
