Di-mu-methoxy-bis[(eta(5)-cyclopentadienyl)(nitrosyl-kappa N)(trimethylsilylmethyl)molybdenum(II)].
The title complex, [Mo(2)(C(5)H(5))(2)(CH(3)O)(2)(C(4)H(11)Si)(2)(NO)(2)], is formed in high yield by treating [CpMo(NO)(CH(2)SiMe(3))(2)] (Cp is cyclopentadienyl) with methanol. The nitrosyl ligands are nearly linear [O[bond]N[bond]Mo 170.1 (4) and 170.1 (5) degrees ], with short Mo[bond]N bonds [1.769 (4) and 1.776 (4) A] and long N[bond]O bonds [1.216 (5) and 1.201 (4) A]. The central four-membered Mo(2)O(2) ring exhibits an average Mo[bond]O bond length of 2.15 A.
