A new and simpler derivation of the equations of the "Already Unified Field Theory" of Maxwell, Einstein, and Rainich is presented. The approach is based on an extension to the manifold of general relativity of the intrinsic tensor techniques described in a previous paper.
Reaction of A 2 CO 3 (A = K, Rb) with Sn and Se in an H 2 O/CH 3 OH mixture at 115Β±130 Β°C affords the isotypic selenidostannates(IV) A 6 Sn 4 Se 11 Β΄x H 2 O (A = K, x = 8) 1 and 2 whose discrete [Sn 4 Se 11 ] 6Β± anions each contain two corner-bridged ditetrahedral [Sn 2 Se 6 ] 4Β± species.
