the problem is if I have repeated derivatives in the equation then the output does not collect it together. Please see updated example cl3 in question.

Wizard {{Derivative[0, 1, 0][R][x, y, z], {B1}}, {Derivative[2, 0, 0][R][x, y, z], {B2}}, {Derivative[2, 1, 3][V][x, y, z], {B4}}, {Derivative[3, 2, 1][R][x, y, z], {B3}}, {Derivative[4, 1, 5][V][x, y, z], {B5}}} is clear and perfect answer what I actually wanted.

@Wizard I want all derivatives and all appropriate coefficients. To know order with which derivative is which coefficient

thank you for your attention but how to know which coefficient is with which derivative? If I will have partial derivatives, I need list of derivatives and list of coefficients parallel to know how to pair them.

how to know which coefficient is with which order of derivatives? Maybe it is better to print list of coefficients and list of derivatives. I need some help about code.

@Nasser It is managed now. Please try it, I think it is working, but how to do that without typing for which derivatives I want coefficient in front. I need it all. For example CoefficientList[cl,derivatives]??
