A new phenylthiourea grafted Mn-Anderson polyoxometalate cluster: Synthesis, crystal structure and characterization

A novel phenylthiourea modified Mn-Anderson polyoxometalate , [N(C 4 H 9 ) 4 ] 3 [MnMo 6 O 18 {(OCH 2 ) 3 CNHCSNHPh}{(OCH 2 ) 3 CNH 2 }] ( 1 ) has been synthesized and characterized by IR, NMR, UV–Vis spectroscopy, thermogravimetric, electrochemical and single-crystal X-ray diffraction analysis. Structural analysis reveals that compound 1 crystallizes in the orthorhombic crystal system , space group Pcab with a  = 17.7477(9) Å, b  = 33.6245(16) Å, c  = 32.322(2) Å, V  = 19288.7(19) Å 3 and Z  = 8. Noticeably, the asymmetric POM cluster with terminal modification could be connected through H-bonding interactions of C H⋯O to form an infinite supramolecular chain. Furthermore, the adjacent 1D chains are linked by H-bonding interactions of N H⋯O to generate a 2D supramolecular layer.
