The (1 : 1) adducts of 5-nitrosalicylic acid (5-nsa) and 2-chloro-3,5-dinitrobenzoic acid (cdnba) with triphenylphosphine oxide (tppo), [(5-nsa)(tppo)] (1) and [(cdnba)(tppo)] (2), have been prepared and their structures determined by X-ray diffraction and reffned to residuals R 0·045 (1) and 0·043 (2) for 2540 and 3265 observed reflections respectively. Crystals of both adducts are monoclinic, space group P21/c (1) and P21/a (2), with 4 dimer units in cells of dimensions a 16·217(1), b 7·6807(8), c 19·697(4) Å, β 113·357(8)° [for (1)] and a 16·009(5), b 8·687(1), c 17·640(5) Å, β 90·30(1)o [for (2)]. In both examples, the two molecules comprising the asymmetric unit are linked by a single hydrogen bond between the proton of the carboxylic acid and the phosphoryl oxygen of tppo [O- - -O, 2·524(3) Å (1); 2·72(3) Å (2)], while, in each case, the additional functional groups of the acid are not involved in any other intermolecular hydrogen-bonding interactions.

Molecular adducts of urea with six aromatic carboxylic acids have been prepared and characterized by using X-ray diffraction methods and infrared spectroscopy. These compounds are with 5-nitrosalicylic acid [(C7H5NO5)2(CH4N2O)] (1), 3,5-dinitrosalicylic acid [(C7H4N2O7)(CH4N2O)] (2), 4-aminobenzoic acid [(C7H7NO2)2(CH4N2O)] (3), o-phthalic acid [(C8H6O4)(CH4N2O)] (4), pyrazine-2,3-dicarboxylic acid [(C4H4N2O4)(CH4N2O)] (5) and pyridine-2,6-dicarboxylic acid [(C7H5NO4)(CH4N2O)2] (6). In the majority of the adducts, all six potential interactive sites on the urea molecules are utilized in hydrogen bonding, giving polymeric structures.

Modifying polyoxometalates with organic and/or metal-organic moieties is a widely adopted method for broading the range of properties. In this work a new polyoxometalate constructed from Anderson-type polyoxoanions and L-arginine (Arg =L-arginine) molecules Na [CrMo6(OH)6O18]}(H2Arg)2·8H2O(1) has been synthesized via conventional method and characterized by routine techniques. Single-crystal X-Ray diffraction analysis shows that compound 1 is constructed by chiralL-arginine grafted Anderson-type clusters, sodium cation and water molecules which are further stabilized by hydrogen bonding interactions constitute 3D supramolecular networks. In addition, both antitumor behavior and photocatalytic activities of compound 1 were investigated.
