Laboratory for solid state and complex compounds chemistry (LSSCCC) has been formed 1. 1. 2009. merging the Laboratory of solid state chemistry (LSSC) and the Complex compounds laboratory (CCL). Both components of today's laboratory were created in the Department of Structural and Inorganic Chemistry, shortly after the founding of the Ruder Boskovic Institute.
The first research in the Laboratory of solid state chemistry were oriented towards semiconductor materials, and then followed intensive research of nuclear fuel. Current research in this group (Project "Metal hydrides in clean energy systems") are mainly focused on the reaction of intermetallic compounds with hydrogen or oxygen. These materials can be used as catalysts, hydrogen storage tanks in an environmentally acceptable energy sources, such as in Ni/MH-batteries, where the metal hydride (MH) replace toxic cadmium. Members of this group are: Dr. sc. Želimir Blažina (project manager), Dr. sc. Antun Drašner, Dr. sc. Goran Miletić, Dr. sc. Andrea Knežević and Ivka Štefanić (technician).
In the Complex compounds laboratory the intensive research of chemistry and stereochemistry of complex compounds of transition metals date from 1970s. In particular, the research included the class of compounds containing direct chemical bond between metal atoms, which lasts to this day (hexanuclear clusters). Immediately after the discovery of high temperature superconductivity 1986th year, in this lab are prepared first high-temperature superconducting oxides in Croatia and this part of Europe, based on the systems La-Sr-Cu-O and Y-Ba-Cu-O, Bi-Sr-Ca-Cu-O (Ln, Ce) - (Nb, Ta)-Sr-Cu-O and Hg-Ba-Ca-Cu-O. Currently in this group (project "polynuclear metal systems: synthesis and properties") the electronic and magnetic properties of hexanuclear clusters of niobium and tantalum [M6X12)L6]n± (X = Cl, Br; n = 2, 3, 4) are under investigation, as well as and polynuclear complex systems with tris(oxalate)metalate(III), [M(C2O4)3]3- (M = Cr, Fe, Mn), and tris(oxalate)oksometalate(V) [MO(C2O4)3]3- (M = Nb or Ta) ions, which serve as connections of paramagnetic ions of transition metals (Co, Ni, Cu, rare earth). Members of this group are: Dr. sc. Pavica Planinić (project manager), Dr. sc. Berislav Perić, Dr. sc. Srećko Kirin, Dr. sc. Marijana Jurić, B. Sc. Lidija Androš, B. Sc. Zoran Kokan and Ernest Sanders (technician).
By returning of Dr. sc. Srećko Kirin from abroad in 2008. and getting projects out of funds "Unity Through Knowledge" (UKF) and the "Croatian Foundation for Science" (HRZZ), in the Laboratory for Chemistry of complex compounds the investigations on organometallic bioconjugates as potential enantioselective catalysts generally interesting in materials science and biomedicine are started. Collaborators on these projects are Dr. sc. Srećko Kirin, Dr. sc. Berislav Perić and Zoran Kokan.
