Description:
Two alkylimido derivatives of hexamolybdate, (Bu 4 N) 2 [Mo 6 O 18 (≡N- o -COOCH 3 C 6 H 4 )] ( 1 ) and (Bu 4 N) 2 [Mo 6 O 18 (≡N- o -COOCH 2 CH 3 C 6 H 4 )] ( 2 ), were synthesized in high purity and good yields by the reaction of [(C 4 H 9 ) 4 N] 4 [α-Mo 8 O 26 ] and methyl anthranilate or ethyl- o -aminobenzoate hydrochloride with N , N ′-dicyclohexylcarbodiimide (DCC) as a dehydrating agent in dry acetonitrile solution, which were characterized by elemental analyses, IR, UV/Vis, and 1 H NMR spectroscopy as well as ESI-MS, and single-crystal X-ray diffraction study. Compound 1 crystallizes in the monoclinic space group P 2 1 / n with one-dimensional chain structure via intramolecular hydrogen bond. Compound 2 also crystallizes in the monoclinic space group P 2 1 / n with dimer structure by intramolecular hydrogen bonds and π–π interactions between the pairs of cluster anions.
