Twelve kinds of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF or ET) cation radical salts with tetrahedrally coordinated zinc(II) complex anions were obtained by electrocrystallization; most of them were produced via the additional reaction of Lewis-basic cyano-containing anions [N(CN)2-, C(CN)3-, and Au(CN)2-] with ZnX2 (X = Cl-, Br-, and SCN-) that occurred during electrocrystallization. On the basis of the charge and arrangement of ET molecules, these salts were predominantly categorized into four groups: (A) isolated ET?+ dimers or tetramers, (B) infinite ET?+ ribbon, (C) infinite layers either with a peculiar ET0.5+ arrangement of ET molecules with partial charges other than +0.5, and (D) infinite layers of ET0.5+ molecules. In A, zinc(II) complex anions including a unidentate-coordinated C(CN)3 or Au(CN)2 group spatially interrupt the infinite arrangement of ET molecules. The ET?+ ribbon in B runs parallel to the pseudopolymeric chain of disordered Zn[C(CN)3]2Br22- ions. In C, two salts are semiconductive, whereas the remaining two salts behave as metallic at room temperature and undergo a metal-insulator transition on cooling. The ET molecules in D are arranged in a θ42+40-like packing motif, due to the nonplanar anionic layers. All salts are semiconductive and exhibit a gradual evolution in their superstructures with cooling associated with charge disproportionation.

Multifunctional phosphonium-lanthanide compounds that simultaneously possess paramagnetism, luminescence, and tumor mitochondrial targeting properties were prepared by use of a facile method. These compounds were fully characterized by use of 1H, 13C, 31P NMR, FT-IR, and elemental analyses. The thermal properties of these compounds including melting points and decomposition temperatures were investigated using DSC and TGA analyses. In addition, the paramagnetism, luminescence, and tumor targeting properties of these multifunctional compounds were confirmed by respective use of SQUID, fluorescence, and cell cytotoxicity studies. All compounds exhibited paramagnetism at room temperature, which could provide target delivery of these compounds to parts of the body containing tumor cells using a strong external magnetic field. In addition, these compounds display two major characteristic emissions originating from Dy3 +, which can be utilized for imaging tumor cells. The IC50 values of these compounds measured against normal breast cell line (Hs578Bst) are significantly greater than those measured against the corresponding carcinoma breast cell line (Hs578T), clearly indicating the selective tumor targeting properties of these compounds. Confocal fluorescence microscopy studies were used to confirm the yellowish-green fluorescence corresponding to the emission of dysprosium thiocyanate anion within cancer cells upon exposure of cancer cell lines such as human pancreatic carcinoma cell line (MIAPaCa-2) and human breast carcinoma (MDA-MB-231) to a solution of these phosphonium-dysprosium compounds.
