The melilite structure consist of pairs of fused T O 4, where T may be Si, Al, B, in bow-tie form. Sharing one corner, the formula of the pair is T2 O 7. These bow-ties are linked together into sheets by the B cations. The sheets are held together by the A cations, most commonly calcium and sodium.
