Effects of p,,-pm conjugation in phosphaalkenes have been considered by taking into account the results of X-ray structural studies and ab initio quantum-chemical calculations. The structural consequences of the conjugation depend to a certain extent on the character of the substituent and the place
## Abstract The molecular structure of 2,2,6,6‐tetramethylpiperidinophosphaalkyne was determined by the X‐ray structural method. The main geometrical parameters are as follows: PC 1.559(2), NC(sp) 1.316(2) Å, PCN 178.9(1)°, with an almost planar trigonal bond configuration for the N atom and th
