Subscribe for occasional emails about new things. Tessellation of self-assembling molecular building blocks is a promising strategy to design metal-organic materials exhibiting geometrical frustration and ensuing frustrated physical properties. Each seven-coordinate, pentagonal-bipyramidal TiIV has a bridging oxide and a phenolate as axial ligands. Module 1: Metrology - Part I. Geometry and Polarity =trigonal bipyramidal, mg=linear Nonpolar. Specifically, the use of the Dy III ion in targeted coordination environments that promote strong uniaxial symmetry stabilizes the largest m J =±15/2 ground state and gives a large separation from the excited m J states within the energy barrier. The Cartesian product of an n-polytope and an m-polytope is an (n+m)-polytope, where n and m are 2 or higher.n-polytope and an m-polytope is an (n+m)-polytope, where n and m are 2 or higher. Direct current (dc) magnetic susceptibilities revealed that compound 1 shows easy-plane magnetic anisotropy (D = +29.9 cm−1, E = 0.31 cm−1) and 2 shows easy-axis magnetic anisotropy (D = −6.6 cm−1, E = 0.02 cm−1). The positive sign of D parameter was verified by experimentally and theoretically [41–47] and further confirmed by high-field electron paramagentic resonance (HFEPR) [49].
