Individual Ge-O bond lengths of 24 germanate tetrahedra in solid materials are observed to increase with decreasing <O-Ge-O>3, the average of the three O-Ge-O angles common to each bond, and with 1/cos(Ge-O-Ge). These correlations are examined in terms of valence electron population analyses obtained from extended Huckel molecular orbital theory.

Bond-length distributions have been examined for eighty-four configurations of the lanthanide ions and twenty-two configurations of the actinide ions bonded to oxygen. The lanthanide contraction for the trivalent lanthanide ions bonded to O<sup>2-</sup> is shown to vary as a function of coordination number and to diminish in scale with increasing coordination number.

Bond-length distributions are examined for three configurations of the H+ ion, sixteen configurations of the group 14-16 non-metal ions and seven configurations of the group 17 ions bonded to oxygen. Lone-pair stereoactivity for ions bonded to O<sup>2-</sup> is discussed, as well as the polymerization of the PO<sub>4</sub> group.
