oktaeederpoor, oktaeedriline poor, oktapoor, oktaeedertühik, oktaeedriline tühik
tühik/poor kristallivõres, mida ümbritsevad aatomid moodustavad oktaeedri (vt kristallivõre tühik; vrd tetraeederpoor), in crystal structures, a lattice void surrounded by six atoms forming the vertices of an octahedron (see: lattice void; compare: tetrahedral pore)
