Resum
The crystal structure of the title compound C22H30N4O2 H2O (L), has been determined using X-ray diffraction at 293 K. The crystal of 1,2-bis[4-(3,5-dimethyl-1H-pyrazol-1-yl)-2-oxobutyl]benzene is in triclinic crystal system with space group P(-1) (Z = 2), lattice parameters a = 8.225(6) A ° , b= 10.967(6) A ° , c=12.903(6) A ° , V = 1119.1(11) A ° 3. Analyses of single crystals of L, crystallized from dichloromethane/diethyl ether (1:1), revealed that the molecules are arranged in couples, which adopt a pseudo chair conformation, by means of intermolecular O-H N hydrogen bonding interactions. Moreover, the extended structure revealed a 1D chain caused by several C-H N intermolecular interactions.
