چکیده
We have investigated cyanide-based metal complexes, which were synthesized by combining [M(CN)4]2- (M = Pt, Pd, Ni) or [MN(CN)4]2- Mn, Re) with complex cations, ions, and organic focusing on their dynamic structures such as thermal expansion (TE) phase transition. For example, FePd(CN)4 is a three dimensional framework consisting of four-coordinate iron(II) nodes. This cyanide demonstrates large anisotropic TE involving negative (NTE) colossal positive (PTE) during 100 K-500 K. Other examples are two-dimensional (2D) undulating layer-type coordination polymers type [M(salen)]2[Ḿ (CN)4] Fe; Ḿ MnN, ReN, Pt(I2)x; x 0.18, 0.45, 0.85, 1.0). Uniquely, they demonstrate composition-dependent including 2D-PTE 2D-NTE wide range linear coefficient values −45~+63 × 10-6 K-1. Furthermore, the combination [MN(CN)4]2-(M an ionic liquid cation, 1-ethyl-3-methylimidazolium (EmIm+), provided melting systems (EmIm)2[MN(CN)4] cyanide-bridged architectures. Moreover, we also developing molecular probes incorporating moieties, that can work in environments cell membranes, to investigate promote membrane functions.
