Figures 3 and 4 clearly depict the Pb and Sr coordinations in artroeite, acuminite, and tikhonenkovite. The Sr coordinations in acuminite and tikhonenkovite differ from the Pb coordination in artroeite in three important ways: (1) each Sr bonds to two H20 groups in lieu of bonding to two octahedralligands;
