	Abstract	A simple, quick and reliable method is derived to calculate values of [(0,F)/Me] for block structures. The method of calculation is exemplified using ideal and real (defect) block structures and inconsistent published data. The method represents a simple means to systematically classify block structures.

	Abstract	Compounds of the systems Fe203-Nb205 (O/Me < 2.5) and Nb205-W03 (O/Me > 2.5) were prepared by chemical transport. The block structures of the obtained phases were investigated by high resolution transmission electron microscopy. The unusual defects observed were nearly identical in both systems. A recently devel-oped method to calculate the O/Me value of block structures [ 1 ] was extended and used for these defects.

	Abstract	Compounds near the composition Nb205: WO3 ~ 6:1 were prepared by chemical trans-port (at relatively low temperatures). The block structures of the obtained samples were investigated by high resolution electron microscopy. Besides unusual defects microdomains were found which still contain edgesharing blocks even at the composition 0/27Me = 2.53 to 2.55.

	Abstract	The hybrid phases N b590 147F and N b650 16iF3 were prepared at high tem perature and investi gated by high resolution transmission electron microscopy. Both phases have block structures. The sample of the phase N b590 147F is very well ordered, w hereas the phase N b650 161F3 shows some defects. In a sample of Nb650 161F3 m icrodom ains of a new 2:1 hybrid phase Nb960 238F4 were found. Structural differences of the systems N b20 5/N b 0 2F and N b20 5/W 0 3 are discussed.
