This talk will discuss the use of oxide-fluoride chemistry to create new frequency doubling materials and theirpotentially-improved efficiencies and absorptions. Noncentrosymmetric oxide-fluoride materials are desired for use asfrequency doublers (FDs): crystals that are able to double the frequency of laser light to obtain higher energy lasersources. Fluoride ions within solid-state early-transition metal oxides can enhance the efficiency of the FD responseand blue shift the absorption of the material so that the material does not absorb laser light in the FD process.Absorption of the laser light can both damage the crystal and decrease the FD. Typically, noncentrosymmetriccompounds are synthesized with polar units (such as early-transition metals). We examined the distorted anion of[VOF4(H2O)]2- within the series of compounds MVOF4(H2O)7 (M2+ = Co, Ni, Cu, Zn). CuVOF4(H2O)7 was the onlycompound to crystallize in a noncentrosymmetric space group owing to the packing of bent units and exhibit FDbehavior. It is also possible to synthesize polar materials from racemates. One such material is[Cu(H2O)(bpy)2]2[HfF6]2�3H2O that has ?- and ?-[Cu(H2O)(bpy)2]2+ cations arranged so that only mirror or glideplanes relate the two enantiomers which is a condition to observe the polarity
