摘要
The structure of the mineral jinshajiangite from the Norra Kärr alkaline complex (Sweden) was determined by single-crystal X-ray diffraction and refined to R = 6.7%. The monoclinic unit-cell parameters are a = 5.350(2) Å, b = 6.909(6) Å, c = 20.96(1) Å, β = 99.83(4)°, sp. gr. P2/m. This mineral is an Fe-rich analogue of surkhobite and perraultite, but it crystallizes in a different space group, and the unit-cell parameters a and b are two times smaller than those of these two minerals. The framework of jinshajiangite from Norra Kärr contains narrow and wide channels, which are occupied by Ca, Na, Ba, and K atoms in an ordered fashion.
