..., except for the tetrahedra, which are connected by vertexes with other polyhedra. Despite the similarity in composition with carmeltazite, ZrTi 3+ 4 Al 2 O 11 , the structures of the two minerals bear little resemblance to one another, most notably the number and type of cation-oxygen polyhedra. Instead...
