    “…Each P atom is attached to two substituents located up and down with respect to the plane of the phosphazene ring, the central P(3)N(3) ring having a twist-boat conformation. The three O/P/O planes and five of the six benzene rings are nearly perpendicular to the mean plane through the phosphazene ring [dihedral angles = 82.98 (8)–88.92 (8)°], while the remaining benzene ring forms a dihedral angle of 25.72 (7)°. …”

    “…In this study, photocatalytic experiments of 20 mg l(−1) sulfamethazine (SMN) in aqueous solution containing ZnO with different morphologies, tetra-needle-like ZnO (T-ZnO), flower-like ZnO (F-ZnO) and nanoparticles ZnO (P-ZnO), were performed. The results indicated that photocatalytic degradation of SMN was effective and followed the pseudo-first-order reaction, but the degree of SMN mineralization showed obvious differences using ZnO with different shapes. …”

    “…The low- and high-frequency oscillations in DMMP and DIMP are assigned to coherent excitation of the symmetric O–P–O bend and P–C stretch, respectively. The observation of the same ionization-induced coherently excited vibrations in related molecules suggests a possible common excitation pathway in ionized organophosphorus compounds of biological relevance, while the distinct oscillatory dynamics in each molecule points to the potential use of FTRMS to distinguish among fragment ions produced by related molecules.…”

    “…Treatment of HOAr(P) with Ln(III)[N(SiMe(3))(2)](3) (Ln = La, Sm, Y, Yb) in a 3:1 molar ratio yielded the mononuclear rare-earth metal complexes Ln(III)(OAr(P)-κ(2)O,P)(3) (2-Ln). The heterobimetallic rare-earth metal–silver complexes Ln(III)(OTf)(μ-OAr(P)-1κ(1)O,2κ(1)P)(3)Ag(I) (3-Ln) were prepared from monometallic precursors by reactions of equimolar amounts of 1 with Ln(III)[N(SiMe(3))(2)](3) or 2-Ln with silver(I) triflate, respectively. …”
