Is there any co-ordinate bond in P4O10.​yes or no tell me with structure​​​​

thats called JDLee and places where NCERT (which some people call godbook all over the net, with no reason for reactions, its impossible to study if you are actually studying for iit) fails …these are some very common and extremely important structures and compounds...yeah it does structure is exactly same as p4o6 with each p atom makind a sigma dative bond towards oxygen and oxygen making a ppi-dpi back bond towards phosphorous, so in effect a double bond but vastly different that ethene , each p at corner of tetrahedral with an o in between each
