Research in the Hamaker group is currently focused on
coordination chemistry and catalysis. The research projects
bridge the traditional areas of organic and inorganic chemistry,
with exposure to analytical analysis techniques. There are two
major projects currently under investigation: (1) the synthesis
of new ligands and transition metal complexes and the
investigation of the utility of the new ligands anc complexes;
and (2) the investigation of intermolecular interactions,
especially hydrogen bonding, in the solid state (crystal
engineering). The group also has active collaborations with
faculty members in the departments of Biological Sciences and
Agriculture here at ISU. The current projects will allow
students to encounter many synthetic and analytical techniques.
Modern spectroscopic techniques including NMR, IR, UV/vis, X-ray
crystallography, and electrochemistry are used to characterize
the new compounds. Additionally, chromatographic techniques
including GC, GC/MS, TLC, and column chromatography are used for
identification, quantification, and isolation of catalytic
products.
Project 1: Synthesis of new ligands and metal complexes
and their uses. Our first project is the development of new
ligands such as those pictured below for the synthesis of novel
metal complexes. We are interested in characterizing these new
ligands and their metal complexes. Potential uses of the ligands
and complexes include new photosensitive/photoreactive inorganic
compounds, catalysis, and the synthesis of the removal of toxic
heavy metals and the recovery of catalytically active noble
metals. We are also interested in studying the
structure/property relationships of our new metal complexes. Our
group has synthesized several new monomeric and dimeric
ruthenium complexes with the general formula [(η6-arene)RuCl(NS)][X].
We are interested in exploring catalytic reactions of complexes
of these new ligands with several metals, including ruthenium,
platinum, palladium, rhodium, copper, and vanadium.
Project 2: Solid state intermolecular interactions
(crystal engineering). Intermolecular forces, such as
hydrogen bonds and π-stacking, play an important role in
both the reactivity and the crystal packing of molecules.
Additionally, the physical properties of a substance
(including density, color, solubility, etc.) are determined
by the intermolecular interactions in the crystalline solid
state.
 Our group is interested in synthesizing simple
molecules with potential hydrogen-bond donor and acceptor
groups and examining their solid state structures. The
compound 3-acetyl-7-diethylaminocoumarin displays both
hydrogen bonding and Type-II carbonyl-carbonyl interactions
in the solid state. We have prepared several hydroxy-substituted
imines and have found the the imine nitrogen is an excellent
H-bond acceptor. We are also investigating the
intermolecular interactions of the substituted
salicylidenecarbazate ligands, which display interesting
intermolecular interactions in the solid state.
