This patent describes a process for converting methane to at least one higher order hydrocarbon comprising contacting a gaseous reactant comprising methane and oxygen with a molybdenum-tungsten-containing catalyst under reaction conditions for an effective period of time to form the higher order hydrocarbon. The catalyst comprising a molybdenun-tungsten-containing complex is represented by the formula Mo/sub a/W/sub b/M/sub c/A/sub d/O/sub e/ wherein M is selected from the group consisting of one or more metals selected from any of Groups IB, IIB, IVB, VB or VIII of the Periodic Table and/or one or more of Y, Cr, Mn, Re, B, In, Ge, Sn, Pb, Th or U, or a mixture of two or more of the metals in the group; A is at least one metal selected from the group consisting of alkali metals, alkaline earth metals, Lanthanide series metals, La, Tl, or a mixture of two or more of the metals in the group; a is a number in the range of from about 1 to about 200; b is a number in the range of from about 1 to about 200; with the proviso that either Mo or W is in excess of the other, the ratio of a:b being about 4:1 or greater, or about 1:4 or less; c is a number such that the ratio of c:(a+b) is in the range of from 0:100 to about 10:100; d is a number such that the ratio of d:(a+b) is in the range of from 0:100 to about 75:100; and e is the number of oxygens needed to fulfill the valence requirements of the other elements.
