چکیده

The title compound, [Mo(4)(C(16)H(20))(2)O(8)]·6H(2)O, is a centrosymmetric ansa-molybdocene complex in which two dinuclear [C(2)Me(4)(η(5)-C(5)H(4))(2)]Mo(μ(2)-O)(2)MoO(2) units dimerize by forming two μ(3)-O bridges between three Mo atoms. The ansa-molybdocene [C(2)Me(4)(η(5)-C(5)H(4))(2)]Mo unit has a typical bent-sandwich metallocene structure with an inter-ring angle of 127.98 (8)°. The Mo atom in the bridging (μ(2)-O)(μ(3)-O)(2)MoO(2) group has a distorted trigonal-bipyramidal coordination. The Mo-(μ(3)-O) and Mo-(μ(2)-O) bond distances inside the units [2.0869 (14) and 2.1014 (15) Å, respectively] are slightly longer than the Mo(-x + 1, -y + 1, -z)-(μ(3)-O) bond distance between the units [1.9986 (14) Å]. The solvent water mol-ecules together with complex O atoms form a network of O-H⋯O hydrogen bonds.

The title compound, [Sn(4)(C(4)H(9))(8)(C(15)H(12)NO(3))(2)(CH(3)O)(2)O(2)], is a centrosymmetric dimer and displays a ladder type structural motif. There are four Sn(IV) centres which can be divided into two sorts, viz. two endocyclic and two exocyclic. The endo- and exocyclic Sn(IV) centres are linked by bidentate deprotonated methanol and μ(3)-O atoms. Each exocyclic Sn(IV) centre is also co...
