【 摘 要 】

The reaction of bis(cyclohexylammonium) 4-nitrophenylphosphate with Me3 SnCl (1:2) under reflux in ethanol yielded the title compound 4-NO2 C6 H4 PO4(SnMe3)2·H2 O (1). The X-ray crystallographic analysis achieved on single crystals obtained by slow evaporation at room temperature revealed the formation of an unexpected supramolecular coordination network. The elementary building block can be viewed as two Me3 Sn moieties linked by a bridging 4-nitrophenylphosphate ligand. The two tin atoms are five-coordinated and describe a trans-Me3 SnO2 geometry in a trigonal bipyramidal arrangement. However, the Sn atoms are distinct, exhibiting two different environments. Thus, one is linked to two axial oxygen atoms from two distinct phosphato groups, whereas the other is bound to one phosphato oxygen atom and to a water molecule. From a supramolecular point of view, the combination of the tridentate binding mode of 4-NO2 C6 H4 PO4 and the additional formation of intermolecular hydrogen bonding interactions between NO2/H2 O and PO4/H2 O groups gives rise to a three-dimensional lattice network.
