摘要：
The hydrothermal reaction Of MoO3, CuSO4 center dot 5H(2)O, 2,2':6':2 ''-terpyridine (terpy) and bis-N,N-(methylphosphonic acid) amine (H2O3PCH2NHCH2PO3H2) provided blue crystals of the bimetallic oxide [{Cu(terPY)}(2)Mo6O17(H2O)(O3PCH2NH2CH2PO3)(2)] center dot H2O (1 center dot H2O). The three-dimensional structure of 1 is constructed from {Mo6O17(H2O)(O3PCH2NH2CH2PO3)(2)}(4-) clusters linked through {Cu(terpy)}(2+) subunits. The cluster consists ofthree pairs ofedge-sharing (MoO6) octahedra linked through corner-sharing interactions into a (Mo6O6) ring. One phosphonate ligand spans the diameter of the ring, bridging four molybdenum sites and leaving at a pendant {P=O} group at each terminus. The second cliphosphonate ligand exploits one {-PO3} unit to cap the hexamolybdate ring and bridge all six molybdenum sites while the second {-PO3} terminus bridges two molybdenum sites, leaving a pendant {P=O} unit. Crystal data: C34H45Cu2Mo6N8O35P4: monochnic, P2(1)/n, a = 11.9431(7) angstrom, b = 17.382(1)angstrom, c = 27.524(2)angstrom, beta = 90.429(1)degrees, V = 5713.7(6) angstrom(3), Z = 4, D-calc = 2.270 g cm(-3), R-1 = 0.0466.
