The solid state structure of dilithium tetraphenylporphyrin bis(etherate) has been determined by X-ray crystallography. The structure shows the lithium atoms are displaced out of the plane of the porphyrin, each coordinated in a square pyramidal fashion to the four nitrogen atoms in addition to a molecule of diethyl ether. The lithium atoms are identical, as required by the crystallographic inversion centre. X-ray data are as follows: [Formula: see text] (# 2) with a = 10.1908(4) Å, b = 11.6553(4) Å, c = 12.5199(5) Å, α = 111.644(1)°, β = 98.029(1)°, γ = 111.883(1)°, V = 1214.61(9)Å3, dcalc = 1.171 g cm -3 and Z = 1.
