    • A nonlinear optical material includes a noncentrosymmetric crystal of an anionic boron complex salt containing a cation and at least one organic ligand coordinated to a boron atom. The nonlinear optical crystal may consist of a compound having the formula A[BC.sub.2 ] where A is a monocation, B is boron, and C is the organic ligand, or a compound having the formula A[BC.sub.2 ].sub.2 where A is a dication, B is boron, and C is the organic ligand. The organic ligands may also be organic molecules having .alpha.-dihydroxy functionalities. Furthermore, the organic ligands may be selected from the group consisting of .alpha.-hydroxy carboxylic acids and 1,2-diols or from the group consisting of d-malic acid, d-lactic acid, d-tartaric acid, dimethyl-d-tartrate, diethyl-d-tartrate, l-malic acid, l-lactic acid, l-tartaric acid, dimethyl-l-tartrate, diethyl-l-tartrate, and ethylene glycol. The anionic boron complex may be selected from the group consisting of boro-di(l-malate), boro-di(l-tartrate), boro-di(l-lactate), boro-di(diethyl-l-tartrate), boro-di(methyl-1-tartrate), boro-di(d-tartrate), boro-di(d-lactate), boro-di(diethyl-d-tartrate), boro-di(dimethyl-d-tartrate) and boro-di(ethylene glycolate). The cation may be selected from the group consisting of alkali metals, alkaline earth metals, ammonium ions, and Group 2B dications. The cation may be further selected from the group consisting of lithium, sodium, potassium, the ammonium NH.sub.4.sup.+ ion, the guanidinium C(NH.sub.2).sub.3.sup.+ ion, calcium, and zinc.
