چکیده    The structure of n,n'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, c19h22n2o2, has been studied at low temperature (120k) by means of single-crystal x-ray diffraction. solving the structure shows an orthorhombic unit cell, with p212121 space group, z = 4,a = 6.1046 (4) å, b = 15.8349 (11) å, c = 17.2898 (12) å and v = 1671.3 (2) å3. there are two relatively strong hydrogen bonds (average o—h···n, 2.59 å), involving the hydroxyl group and the nearest n atom of the imine groups is an indicative of intra-molecular hydrogen bonding within each salicylideneimine moiety. c-h…(pi) interactions connect the neighboring molecules together, stabilizing the crystal network. no significant π-π interactions are present in the crystal structure.
