A well-shaped sinoite crystal was milled out of a polished thin section of the Neuschwanstein (EL6) chondrite. The structure was refined on the basis of X-ray single crystal data:Cmc21, a=885.66(18), b = 549.61(11), c = 484.23(10) pm, R1 = 0.0282, 491 F2 values, 26 variable parameters. The structure consists of a complex three-dimensional network of corner-sharing SiN3O tetrahedra (Si-O 161.9, Si-N 171.9-172.8 pm). The crystal chemical peculiarities of Si2N2O are briefly discussed.
