The novel polyoxometalate, 32[Mo8ⅣMo4ⅤV2ⅣO38(PO4)], was synthesized and characterized by elementary analysis, EPR, IR spectra and X ray diffraction. The compoundcrystallizes in triclinic system, space group with a= 1.41999(2)nm, b=1.43467(2)nm, c=1.694610(10)nm, α=95.7250(10)°, β=92.2110(10)°, γ=92.6060(10)°, V=3.42829(7)nm3, Z=2, Dc=2.388g·cm-3, Mr=2465.10g·mol-1, μ=2.489mm-1, F(000)=2388, R1=0.0584, wR2=0.1461, S=1.164. The heteropolyanion is a bi capped pseudo Keggin complex. CCDC: 186645.

The properties of excited states and second-order nonlinear optics for supramolecule [(H2N)2+C- NH(CH2)3CH(NH3)+COO-H2PO4-H2O] from L-arginine phosphate monohydrate (LAP) crystals were calculated by using the CIS and finite-field RHF methods, respectively. The results revealed that the second-order nonlinear optical (NLO) response for this crystal originates largely from the contributions of intramolecular charge transfer of arginine, and the intermolecular charge transfer between arginine and H2PO4- plays an important role as well. The conclusion can help to understand the origin of NLO response in the inorganic-organic hybrid materials.
