Scientific Cooperation with Chile
(DFG/CONICYT: 444 CHL-113/35/0-1)

This project originates from an earlier cooperation with Prof. Dr. Evgenia Spodine (Universidad de Chile)^[1,2]. The exchange program for scientists is supported since 2009. Project leaders: Prof. Dr. Evgenia Spodine (Universidad de Chile), Dr. Diego Venegas Yazigi (Universidad de Santiago de Chile), Prof. Dr. Rüdiger Kniep (MPI-CPfS) and Dr. Raul Cardoso-Gil (MPI-CPfS). The exchange program also includes young scientists (Diploma- and Doctoral Theses).

The aim of the common project is to intensify the cooperation between the groups in the field of inorganic-organic hybrid materials. Special attention is turned to the synthesis and characterisation of compounds with peculiar magnetic properties. This includes the preparation of novel (also nano-scaled) materials with magnetic properties which can be optimised by variation of their topological parameters (ligands, coordination polyhedra, rigid or flexible arrangements of complex anions, as (e. g.) known from borophosphates).
